Add startup performance logging and wallet sync progress UI

Browse Source 
Instrument AppInit2 with StartupPerfLog timing for each startup phase
(block index, wallet load, rescan, tor, peers, etc). Show queued
transaction count in the progress bar during wallet history sync.
Emit transactionSyncProgressChanged for real-time pending counts.
