Move GetStakeWeight() off the UI thread by caching in the staking
miner thread. Replace blocking LOCK(cs_vNodes) with TRY_LOCK in
clientmodel and staking icon updates. Fix out-of-sync label getting
stuck when disconnected. Add daemon bootstrap and faster IBD pipeline.

Major sync performance overhaul:
- Assumevalid: skip FetchInputs/ConnectInputs for blocks below
checkpoint (2,186,940). Only write txindex entries. Eliminates
millions of LevelDB reads during initial sync.
- Skip SyncWithWallets during IBD with automatic post-IBD wallet
rescan from genesis and SecureMsg chain scan.
- Skip wallet best-chain locator update during IBD so restarts
trigger proper rescan.
- Remove send/receive buffer limits (were 1MB/5MB, now unlimited).
The 1MB send buffer was the root cause of ~180 block stalls -
ProcessMessages stops reading when nSendSize >= SendBufferSize().
- Reduce IBD pipeline batch from 500 to 100 blocks for faster
re-requesting with near-instant block processing.
- Seed getblocks limit raised to 20000 during IBD (was 500).
- Faster message handler polling during IBD (10ms vs 100ms).

Critical fix: revert initial sync from getheaders back to getblocks.
The headers-first change (05b1fd1) broke chain continuation — after
downloading the first 2000 blocks, fresh nodes would stall because
the getheaders path has no orphan-based continuation mechanism.
The getblocks/inv/orphan cycle is required for full chain sync.
Also adds getblocks fallback to the headers handler so if headers
are used via other paths, sync still continues.
Other changes:
- Extract REST API into separate rest.cpp/rest.h
- Add REST rate limiting and CORS support
