fix: resolve auto-boss signature mismatch, expose full CP, cap auto-buy, show unlock hints

Closes #148: clear stale signature after each boss fight so subsequent auto-boss pre-saves don't send a mismatched HMAC. Closes #151: auto-buy skips non-max-tier adventurers once they reach 100, keeping gold flowing to the highest-unlocked tier. Closes #152: introduce computePartyCombatPower() in tick.ts mirroring the server-side formula (global upgrades, prestige, equipment, set bonuses, echo, crafted, companion). Resource bar, auto-quest gate, and boss panel all now use the same multiplier-accurate value. Closes #146: tick engine auto-unlocks adventurer-specific upgrades when their adventurer is first recruited; upgrade panel shows a recruit hint for locked entries with no boss/quest source.
fix: resolve sync count inflation, add essence/s display, sort auto-buy by level
