Add biome-ignore backpressure script, convert modals to native <dialog>

Adds scripts/check-lint-ignores.mjs with four enforcement mechanisms:
ratcheting count cap (12 source / 3 test), banned rule prefixes,
required justification, and separate test thresholds. Wired into
pnpm check.

Converts player-management and create-player-modal from div-based
modals to native <dialog> with showModal()/close(), removing 8
biome-ignore comments. Remaining ignores are legitimate (Biome
false positives or stopPropagation wrappers with no fitting role).
