The ring-based flash relied on ring-accent and a CSS transition that never
restarted on a repeat message, so it was effectively invisible. Replace it with
a keyed inset-glow overlay (animation replays on every flash counter bump, and
inset shadow isn't clipped by the window's overflow-hidden) — flashes whether
the window is expanded, freshly auto-opened, or minimised.
The Messages UI trusted only the per-device IndexedDB key, so if the server's
key record was gone (deleted, DB-restored, admin-reset) while a stale private
key lingered in the browser, the app looked 'unlocked' but no one could be
messaged and no setup was offered. Add useKeyState (server 'configured' AND
local unlock): show setup when the server has no key (setup overwrites the stale
local key), unlock when it has one this device hasn't opened, ready otherwise.
ChatThread is now self-contained. Also fix the header title on the Messages and
Notifications pages (was falling through to 'Channel manager').
The live-message push now carries both parties, so an incoming message opens
that conversation's dock window if it's closed, or flashes it once if it's
already open (expanded or minimised, without disturbing the minimised state) —
only for messages from someone else, never your own echo.
Dock state (open windows + minimised state) is persisted per user, so a reload
restores exactly what was open, minimised, or closed.
Move messaging out of the notification center into its own left-nav module
(own page, own unread badge), so a reload returns to it and notifications stay
separate. Add a Messenger-style floating dock (bottom-right): pop a conversation
out from the page, keep chatting across navigation, minimise (rollup) or close.
- Messages is now a routed page; NotificationsPanel reverts to inbox-only and the
nav badge no longer mixes in messages.
- Extract shared KeyGate + ChatThread (used by both the page and dock windows);
e2ee exposes a shared unlock subscription so page and dock agree.
- ChatDock (always mounted for human users) owns the app-wide live-message
subscription and per-device key restore. EN/HU/DE strings.
