satoshi 83d70b2636 Fix accelerator revenue impact always showing zero
The old approach compared coinbasevalue from two getblocktemplate
calls, but new mempool arrivals between calls masked the displacement
loss. Now uses a single template snapshot to find the marginal
(lowest fee-rate) transaction that would be displaced and reports
its fee as the revenue cost.

satoshi dc7da6ab19 Add transaction accelerator (prioritisetransaction UI + API)
Full-stack feature for boosting transactions via bitcoind's
prioritisetransaction RPC:

Backend:
- New accelerator package with Accelerate, Cancel, MaxFeerate, List,
  and background Cleanup goroutine (removes confirmed/dropped txs)
- RPC wrappers: GetMempoolEntry, PrioritiseTransaction,
  GetRawMempoolVerbose, IsRPCError helpers
- SQLite boosted_txs table for persistence across restarts
- Revenue impact measured via getblocktemplate before/after comparison
- Hard cap at 2000 sat/vB; MaxFeerate uses fees.base (not modified)
  to ignore our own prior priority adjustments

Frontend:
- Rocket icon in header with 10s jiggle animation
- AcceleratorPage with flame-gradient border, txid input, feerate
  input, "Prioritize above all" button with spinner, boost list with
  cancel buttons, and dismissible error/success messages
- Hash-based routing (#/accelerator)
- SharesBar font size bump
