feat(esx_ambulancejob): add persistent death state and Medal.tv clip support

[N0tNvll]

Description

This PR improves esx_ambulancejob death handling by making player death states persistent across reconnects and adding automatic Medal.tv clip saving on player death.

The changes introduce:

• Persistent death timestamps using player metadata.
• Automatic restoration of the death state after reconnecting.
• Improved handling of death, revive, respawn and admin revive commands.
• Optional Medal.tv integration to automatically save death clips.

---

Motivation

Previously, a player's death state was only tracked during the current session. If a player disconnected while dead and reconnected later, the death state could be lost and timers would not resume correctly.

This update ensures that:

• Players who reconnect while dead continue their existing death timer.
• Death information is stored reliably in the database and player metadata.
• Duplicate death events are prevented.
• Admin and automated revive flows correctly clean up persisted death data.

The Medal.tv integration provides players with automatic clips of important death events without requiring manual recording.

Implementation Details

• Added persistent death handling through a new persistDeathStatus server function:

  • Updates the users.is_dead database field.
  • Stores the death timestamp in player metadata.
  • Clears the metadata when the player is revived.

• Added a new esx_ambulancejob:requestDeathRestore event:

  • Checks if the player was dead before disconnecting.
  • Restores the death state after spawning.
  • Calculates elapsed time since death and resumes the correct timers.

• Updated client death flow:

  • OnPlayerDeath and StartDeathTimer now support elapsed death time.
  • Prevents duplicate death initialization.
  • Removes redundant death status updates from client-side revive and respawn logic.

• Added Medal.tv integration:

  • Added a new configurable Config.Medal section.
  • Sends death events through Medal's local Events API.
  • Added NUI bridge files for communication with the Medal desktop application.
  • Enabled by default but can be disabled through configuration.

• Improved revive handling:

  • Admin revive commands now properly clear persisted death states.
  • txAdmin healing events also restore the correct state.
  • Dead player tracking is cleaned up consistently.
