v3.2.1 - Saved Media Support for Edit Last Broadcast

[3.2.1] - 2026-06-13

Added

• Added support for editing last broadcast messages with media loaded from data/{adminId}/media.txt.
• Added compatibility for passing saved media values / botApiFileId into editLastBroadcastForAll().

Changed

• Relaxed the $media parameter in BroadcastManager::editLastBroadcastForAll() so it is no longer limited to ?array.
• Edit-last-broadcast flow can now reuse the same saved media format used by regular broadcast sending.

Notes

• Passing null as media keeps the existing media unchanged.
• Passing a saved media value attempts to update the edited message media/caption.
