release: harden provider rotation and download recovery

Apply account and provider changes to active conversions without restarting, isolate API and Web state, and abort the exact fallback attempt when settings change.

Bound resume recovery, make disk reservations abortable, preserve cleanup totals and history, stabilize compact UI state, and canonicalize RapidGator host aliases.

Expand bounded support diagnostics while redacting account identities, local paths, package names, and file names from current and rotated logs.

Add regression coverage for rotation, live settings, HTTP 416 recovery, disk waits, cleanup, context menus, history failures, and support bundle privacy.
