fix: presence MaxListeners leak + self-host fonts to fix tracking prevention
CI / Build & Quality Checks (push) Successful in 10m29s
Trigger Desktop Build / trigger (push) Successful in 5s

Presence: subscribe on MatrixClient (mx) instead of individual User objects.
User EventEmitters have a 10-listener default; the same user appears in many
mounted components simultaneously (member list, avatars, presence rings) and
was accumulating 11+ listeners per event, causing MaxListenersExceededWarning
on User.presence, User.currentlyActive, and User.lastPresenceTs.

Fonts: download JetBrains Mono and Fira Code latin subsets to public/fonts/
and replace Google Fonts CDN links (two external origins) with a local CSS
file. Windows WebView2 tracking prevention was blocking googleapis.com and
gstatic.com, logging 18+ "blocked" warnings per session. VT323 remains on
Google Fonts as it's decorative and not a default option.
