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
