buildR2Key fell back to a static "uploads" namespace (and "video" slug) when
no torrent info-hash was available, so two distinct URL-first uploads sharing a
filename produced the SAME R2/S3 key — the second silently overwrote the first
object while the first video note still pointed at that URL (data loss).
WebTorrent uploads were already safe because the info-hash namespaces the key.
Add computeStorageContentHash(file) in js/r2.js: when no info-hash is present it
derives a deterministic content-based namespace — full SHA-256 of the bytes for
files ≤512 MB (idempotent: re-uploading the same file reuses the key), and a
SHA-256 fingerprint over name/size/mtime + sampled head/tail bytes above that,
so we never buffer a multi-GB video in memory. Wired into BOTH upload paths
(r2Service + s3UploadService) via a new storageIdentifier kept separate from the
info-hash, so magnet generation is unchanged.
Test: tests/storage-key-collision.test.mjs (distinct same-named uploads get
distinct keys; same content is idempotent; large-file fingerprint path samples
edges without buffering and stays deterministic). Full unit suite green.

- `handleVisibility` only scheduled intervals but didn't trigger an immediate refresh when returning to the tab.
- This caused `tests/unit/services/exploreDataService.test.mjs` to fail (assertion `0 !== 1`).
- Added explicit calls to `refreshWatchHistoryTagCounts` and `refreshTagIdf` when `document.hidden` becomes false.

- Modified `loadLegacyR2Settings` to check `localStorage` if IndexedDB is empty.
- Implemented immediate migration of settings from `localStorage` to IndexedDB upon access.
- Added logic to clear `localStorage` after successful migration to prevent secret exposure.
- Verified fix with reproduction script and regression tests.

- Removed requirement for Cloudflare API Token, Zone ID, and Worker Token from Upload Modal and R2Service.
- Simplified R2 configuration to require only Account ID, S3 Access Keys, and a user-provided Public Bucket URL.
- Added a read-only field in Upload Modal displaying the derived target bucket name (npub-based) for user reference.
- Implemented client-side torrent info hash calculation using `WebTorrent` (via `js/utils/torrentHash.js`) to generate magnet links before upload.
- Added a visual upload progress bar to the Upload Modal.
- Updated `js/r2.js` to ensure the Public Bucket URL always includes the `https://` protocol.
