Linus Rath e720be7e17 feat: let users install their own plugins, with admin review of the actual code
The admin page offered "User Plugin Uploads" and "Require Admin
Approval", but nothing in Settings used them: there was no upload, no
uninstall and no way to ask for approval, and the admin had no list of
requests. The approval code that existed pinned a hash of the code only
and showed the admin a manifest the browser sent, never the code.

Now:
- Settings > Plugins has an install button (when uploads are allowed),
  a remove button for the user's own plugins, and lists in plain
  language what each plugin may do, high-risk items first
- an install sends the ZIP to the server, which reads the manifest and
  code itself and pins the request to a hash of both
- the admin Plugins tab lists requests with the code and approves or
  denies them; a user may have 10 open requests
- a user plugin is checked again on every start, so a revoked approval
  or turning user plugins off takes effect
- the consent dialog and the plugin settings are translated, use the
  theme colours, and show the sites a plugin may send data to

Linus Rath 9b9b4f7ef1 fix: reject cross-origin writes to the JMAP passthrough and other cookie-authed routes (GHSA-9mvj-98f5-9q6g)
The origin gate in the proxy only covered `/api/auth/*`. The JMAP
passthrough, `/api/settings`, `/api/wopi/launch`,
`/api/plugin-approval-status`, `/api/fetch-ical`, `/api/translate`,
`/api/caldav/discover`, `/api/calendar-agenda` and `/api/webdav` all act
with the session cookie and had no origin check. A page on a same-site
sibling origin receives SameSite=Lax cookies, so it could run arbitrary
JMAP as the signed-in user, including sharing mailboxes to a third
account.

The proxy now gates every `/api/` route except the WOPI file endpoints
the office editor calls server-to-server, and each of these handlers
checks again. The proxy also decides on the decoded path, so an escaped
spelling such as `/api/%61uth/session` no longer skips the gate.
