feat(meetings): call log, past pagination + date filter; last-seen exact time (batch83)

#7 The past list was hard-capped at 12 (a .slice(0,12) in the client) and there was NO record
   of how many people were ever in a finished call — so the "only calls with >2 people" rule
   was impossible to apply. Added a call_history table: signaling tracks the HIGH-WATER
   participant count per room and logs the call when the room tears down (scheduled meetings
   are skipped — they already have their own row).
   Past meetings now follow the rules asked for:
     • a plain 1:1 direct call is NOT listed — unless it produced a recording/transcript
       (those already surface as recording entries);
     • a call that ever held MORE than 2 people IS listed (e.g. a 1:1 a third person joined),
       showing its participant count and duration;
     • entries are visible only to people who were actually in the call (or the group).
   Server-side pagination (10/page) + a from/to date filter; nothing is double-listed.

#2 Last seen now shows the exact time/date, WhatsApp-style — "last seen today at 1:36 PM",
   "last seen yesterday at 10:15 AM", "last seen 14/07/2026 at 9:00 AM" — instead of "10
   minutes ago".
