Paladium Bot v100.3.48

- Manager Uploader file/folder views now omit protect_content for managers, so screenshot/save/forward are available to managers.
- Removed uploader admin live getChat round-trip from file metadata view.
- Added APCu cache for watermark folder resolution.
- Added DB-backed temporary multi-upload queue to avoid re-serializing the growing batch state on every uploaded item (fixes O(n^2) state writes).
- Exact queue item deletion now deletes only the requested queue_id.
- Queue is cleared on cancel and moved into state only once at “finish upload”.
- Existing watermark delivery/cache behavior remains intact for member/public media sends.

Static tests: PASS (74 PHP files lint, ZIP integrity).
Live Telegram/production DB test: NOT RUN in this environment.
