Themes and tweaks from the catalog (#633 by @7w1)

Themes are pulled from a repo now, so you get the full power of CSS instead of a palette. Tweaks are new: CSS overlays that sit on top of whatever theme you are using.

You'll be prompted to migrate to the new system whenever you update, if you choose not to, you'll be limited to the basic dark/light themes. A few additional themes have been added (Rose Pine variantes, Catpuccin) along with some basic tweaks (circular avatars, monochrome avatars, and square stuff).

You can share themes and tweaks. For themes uploaded online, simply hit the copy button in settings and paste the link in chat. If the setting is enabled, a preview will be generated. Third party themes (as defined by the config.json) have prominent warning banners and fetching is disabled by default.

You can also export and share theme files directly, although no previews are generated for these.

If you're intrested in getting a theme or tweak added to the official catalog, contribute to the themes repo linked above! We're eager to add more!

Markdown parser and render updates (#727 by @7w1)

Migrated markdown parsing and rendering to use marked, which should fix most (all?) markdown issues involving lists/nested structures, inconsistent/inaccurate code blocks, escape sequences, and all the other bugs with literally everything.

Added math rendering support via marked and KaTeX, uses standard $$ and $ delimiters. Only renders a subset of latex tags that will likely need to be expanded so feel free to make issues if needed.

Also adds support for sending markdown tables (although they're rendered rather plainly at the moment), sending valid html directly (such as for colored text), and properly escaping anything with backslashes.

Fixes link previews appearing in code blocks, fixes pmp new line behavior, fixes links not opening in new tabs, and fixes editing arbitrary html messages, probably.

Finally, the old WYSIWYG editor has been completely removed.

Change how settings links are shared (#695 by @hazre)

Settings links copied from Sable now stay on the current client URL and include a small Sable marker in the link. That lets Sable recognize settings links copied from other Sable instances without treating unrelated third-party /settings/... links as Sable settings links.

When you send a bare settings link in the composer, Sable now rewrites it into a labeled link so it looks better on non-Sable clients too. For example: [Settings > Account > Display Name](https://client.example/settings/account?focus=display-name&moe.sable.client.action=settings).

Invalid or malformed settings-looking links now stay normal links instead of being shown as settings chips.

If you previously set settingsLinkBaseUrl in config.json, remove it. Sable now derives settings links from the runtime app URL, and the old config key is no longer used.
