Bringing Hometown up to date with mastodon/mastodon (#1371)

This is a massive PR, so apologies for the poor performance viewing it!

This merges in the content of Mastodon 4.3.0. *This PR isn't ready to
deploy to production*, and I don't recommend trying it in a production
environment. Since I started by merging 4.3.0, this will likely have
reverted at least some of the content of the post-4.3.0 security patches
in the 4.2.x series; those will be brought back as I merge in 4.4.0 and
4.5.0.

I haven't yet tested this PR, so it may not actually run without
additional tweaks. I'm putting it up now for discussion and so multiple
people can test if we want.

---

Here's a few notes on things I ran into and thoughts I had while working
on it:

* We may want to look at `server_banner.jsx,` where I ended up undoing
the v3-style rewrite due to the new react component being used. I'm not
sure what the current goal for it is.
* I may not have 100% merged in all content from `status_action_bar`
correctly.
* There's a number of places where I updated the links for remote
usernames, and they should be tested to make sure they work. They're all
`<Permalink>` elements. I have in my notes that `status_content` might
need double-checking.
* I may also not have gotten the spoiler display right in
`status_content`.
* It looks like previous versions of Hometown had customizations to the
`media_item` display, not all of which was preserved as-is due to
surrounding rewrites. I'm not sure what the vision is and could use
another set of eyes.
* The character count rendering clashed with the newly-introduced
handling of a character count variable upstream, and I'm not sure if the
version I've got here 100% works or not.
* The navigation bar was completely rewritten and no longer has the
components Hometown was customizing; did I properly catch any
replacements? Did we handle all links to accounts to make sure they go
to the remote instance?
* Polls: I reverted the single/multiple choice toggle because upstream
has an actual proper UI for this that should be integrated in one of the
versions we’re merging in. Please double-check that the current version
looks fine to you.
* The font icons will need double-checking. Hometown made some custom
use of the font-awesome icons, while Mastodon 4.3.0 replaced
font-awesome with something else. I may not have caught all places that
font-awesome icons were being used.
* We’ll want to make sure the post display is correct, including
Hometown customizations, because the previous static post page has been
replaced with the React one.

-## Pull requests
+## Pull Requests
+
+### Size and Scope
 
-**Please use clean, concise titles for your pull requests.** Unless the pull request is about refactoring code, updating dependencies or other internal tasks, assume that the person reading the pull request title is not a programmer or Mastodon developer, but instead a Mastodon user or server administrator, and **try to describe your change or fix from their perspective**. We use commit squashing, so the final commit in the main branch will carry the title of the pull request, and commits from the main branch are fed into the changelog. The changelog is separated into [keepachangelog.com categories](https://keepachangelog.com/en/1.0.0/), and while that spec does not prescribe how the entries ought to be named, for easier sorting, start your pull request titles using one of the verbs "Add", "Change", "Deprecate", "Remove", or "Fix" (present tense).
+Our time is limited and PRs making large, unsolicited changes are unlikely to
+get a response. Changes which link to an existing confirmed issue, or which come
+from a "help wanted" issue or other request are more likely to be reviewed.
+
+The smaller and more narrowly focused the changes in a PR are, the easier they
+are to review and potentially merge. If the change only makes sense in some
+larger context of future ongoing work, note that in the description, but still
+aim to keep each distinct PR to a "smallest viable change" chunk of work.
+
+### Description of Changes
+
+Unless the Pull Request is about refactoring code, updating dependencies or
+other internal tasks, assume that the audience are not developers, but a
+Mastodon user or server admin, and try to describe it from their perspective.
+
+The final commit in the main branch will carry the title from the PR. The main
+branch is then fed into the changelog and ultimately into release notes. We try
+to follow the [keepachangelog] spec, and while that does not prescribe how
+exactly the entries ought to be named, starting titles using one of the verbs
+"Add", "Change", "Deprecate", "Remove", or "Fix" (present tense) is helpful.

 ## ActivityPub federation in Hometown
 
 Hometown federates just like Mastodon, so the document below (identical to Mastodon's) still applies. The main difference is that any given `Note` object will have a `localOnly` property that is a boolean. While other servers will never see this boolean set to anything but `false` (since by definition these messages are not federated), _clients_ will see this property and can now render a post differently based on whether it is local-only.

+#### WebFinger
 
 In Mastodon, users are identified by a `username` and `domain` pair (e.g., `Gargron@mastodon.social`).
 This is used both for discovery and for unambiguously mentioning users across the fediverse. Furthermore, this is part of Mastodon's database design from its very beginnings.
 
 As a result, Mastodon requires that each ActivityPub actor uniquely maps back to an `acct:` URI that can be resolved via WebFinger.

+## Size limits
+
+Mastodon imposes a few hard limits on federated content.
+These limits are intended to be very generous and way above what the Mastodon user experience is optimized for, so as to accomodate future changes and unusual or unforeseen usage patterns, while still providing some limits for performance reasons.
+The following table attempts to summary those limits.
+
+| Limited property                                              | Size limit | Consequence of exceeding the limit |

+| Serialized JSON-LD                                            | 1MB        | **Activity is rejected/dropped**   |
+| Profile fields (actor `PropertyValue` attachments) name/value | 2047       | Field name/value is truncated      |
+| Number of profile fields (actor `PropertyValue` attachments)  | 50         | Fields list is truncated           |
+| Poll options (number of `anyOf`/`oneOf` in a `Question`)      | 500        | Items list is truncated            |
+| Account username (actor `preferredUsername`) length           | 2048       | **Actor will be rejected**         |
+| Account display name (actor `name`) length                    | 2048       | Display name will be truncated     |
+| Account note (actor `summary`) length                         | 20kB       | Account note will be truncated     |
+| Account `attributionDomains`                                  | 256        | List will be truncated             |
