feat(db): Implement hash deletion functions

This commit introduces functionality to delete hash values from the Dragonfly database. It includes two new functions: `hashDelete` for deleting a hash value by key, and `hashDeleteId` for deleting a hash value by both key and ID.

Key changes:

*   **`fnc_processQueue.sqf`:** Added cases for "hdel" and "hdelid" task types to process hash deletion requests, calling the corresponding `FUNC(hashDelete)` and `FUNC(hashDeleteId)` functions.
*   **`XEH_PREP.hpp`:** Added `PREP` definitions for `hashDelete` and `hashDeleteId` to enable event handlers for these functions.
