ja2-web v1.0.1 - Cloud Locker

Cloud Locker: sign in once, upload your own Jagged Alliance 2 data, and play it from any machine with your saves synced.

Added

• Cloud Locker - sign in and keep your game data and savegames on your account, so
  any machine you sign in from has them. Single sign-on via Google, Discord or
  Microsoft; no password to create. Self-hosters can drop the feature entirely with
  --build-arg CLOUD_LOCKER=0.
• One-time upload wizard in the game: a checklist of the files your account needs,
  ownership confirmation, then one folder pick that finds and uploads everything.
• Two-tier upload verification - an exact checksum match against a known release, or a
  known filename whose size is within 5% (Jagged Alliance 2 shipped in many builds).
  Anything else is refused, so the locker only ever holds game data.
• Uploaded bytes are kept in the browser cache, addressed by content, so the first play
  after uploading reads locally instead of downloading the library back.
• Cloud saves sync automatically as you play.
• Storage works two ways: any S3-compatible object store, or plain local disk when no
  S3 is configured.
• Server-side abuse limits: per-file and per-save size caps, per-account byte and file
  quotas, a whole-install cap, and hard streaming byte ceilings.

Changed

• Signing in goes straight into the game, and the tile always asks which provider to
  use rather than silently resuming the last account.
• Sessions last one browser session, renewing while you play, instead of a month.
• Uploads run four files at a time; downloads report true byte progress.

Fixed

• HTML is served no-store. It previously carried no cache directives at all, so a
  browser could serve a stale index.html - which also pins the content-versioned
  engine path and could therefore point at a build that no longer exists.
• The player's Data folder is found when nested (for example GOG's Linux
  game/Data), not only one level down.
• The allowed file-extension list is derived from the known editions rather than
  hand-written, which had rejected the 109 .jsd files in a real install's TILECACHE.
• Stray markup copied from a sibling project produced a duplicate <canvas>, making
  the game render small and putting unrelated buttons on screen.
