Add FAQ tab and per-user signing key management to leaderboard

Adds a comprehensive FAQ tab (27 questions across 7 sections) covering
setup, signing keys, submission generation, validation errors, metrics,
rate limits, and contact guidance — reducing unnecessary support emails.

Also includes per-user signing key derivation, key request logging,
and admin key request viewer.
