chore(mining): extract pool_stats from mining_stats_t + size guard (code health) (#517)

mining_stats_t embedded a 944 B mining_pool_stats_t, making it ~1160 B and the
dominant object in mining.c's hot-loop BSS region. Extract it to a file-scope
static in mining_pool_stats.c (restoring mining_stats_t to ~184 B) and add a
static_assert capping the size so future growth can't silently re-bloat the
hot region. Also align the S3/AHB per-nonce statics (block2, hw_ctx) to the
64-byte S3 cache line, and correct the stale CLAUDE.md eff figure (wroom32 is
~95% of ceiling, not 65-70%).

Code hygiene, NOT the TA-413 perf fix: a targeted struct-revert recovered ~0%
on-device and wroom32 measures ~95% of its kernel ceiling, so the 3.6% is
unconfirmed. This just keeps the struct lean + caps the class.

Locking unchanged (pool_stats still guarded by mining_stats.mutex). bitaxe
ASIC path verified on-device (boots / mines / pool stats correct).
