fix: TDZ error from panX/panY/scale declared after await, add HTML no-cache 

Root cause: scale/panX/panY were declared with let at line 5014, but
event handlers referencing them were registered before line 2771. Since
the module has top-level awaits (offlineStore.open, sync.initFromCache),
execution yields and events can fire before the let declarations,
causing "Cannot access variable before initialization" TDZ errors.

Fix: hoist scale/panX/panY declarations to before any await statements.
Also add Cache-Control: no-cache for HTML files and immutable for
Vite content-hashed assets to prevent stale bundle caching.
