feat(chat): older-history pagination + full-thread server-side search

Browse Source 
Older messages (beyond the newest 500) now load as you scroll to the top — the
thread endpoint takes a ?before=<created_at> cursor, the client prepends the older
page and preserves scroll position (renderThread keepScroll). _hasMoreOlder stops
paging when a short page returns.

Search now covers the ENTIRE thread, not just the loaded window: new
/api/messages/search (DM + group, LIKE with escaped wildcards) returns all matching
message ids; the client debounces the query, and jumping to a hit older than the
loaded window pages history back (ensureLoadedBack) until the match is in view, then
highlights + flashes it. Cap raised to 500.
