fix: address PR review comments for tctoken lifecycle

- Wire onNewJidStored callback in messages-send.ts so proactively
  fetched tokens are registered in the pruning index
- Batch keystore reads in pruneExpiredTcTokens (1 query instead of N)
- Persist lastTcTokenPruneTs in keystore so 24h throttle survives restarts
- Replace parseInt() with Number() for safer timestamp parsing
- Normalize JIDs via jidNormalizedUser() before LID lookup in
  resolveTcTokenJid to prevent device-suffix mismatches
