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.
