style: apply biome autofixes and resolve remaining lint findingsHEADmain

Auto-fixed cosmetic findings (import ordering, obj["k"]->obj.k, optional
chaining, template literals, Date.now, parseInt radix, useless ternaries/
switch cases). Resolved the non-autofixable rest by hand:

- Senpy: static-only class -> object literal (no this/static reliance).
- app.html: var global shim -> window.global = window (keeps the shim,
  drops the unused-var flag).
- biome-ignore with rationale for the logout document.cookie clear and the
  holodule scrape non-null assertion.

Verified: biome check 0 diagnostics, svelte-check 0/0, 24/24 unit tests.
