Feature Request: Bulk Enable/Disable via Action Dropdown of Live Channels view

[simkin]

Is your feature request related to a problem? Please describe.
Managing large channel lists in v0.8.19 is currently inefficient. When a user needs to enable or disable dozens or hundreds of channels at once, they are forced to toggle each channel manually. This process is time-consuming and tedious when dealing with extensive M3U files.

Describe the solution you'd like
I would like to see two new options added to the "Action" drop-down menu:

1. Enable selected: Sets the status of all currently selected channels to active.
2. Disable selected: Sets the status of all currently selected channels to inactive.

These actions should integrate with the existing checkbox selection logic, allowing users to select multiple rows (or use 'Select All') and apply the status change in a single click.

Describe alternatives you've considered

• Manual Toggling: The current method of clicking every single channel, which is not user friendly.
• External Scripting: Editing the raw M3U file via regex or text editors, but this bypasses the editor's validation and UI benefits.
• Individual Toggle Buttons: While functional, they do not solve the need for bulk processing.

Additional context
Use case: disable all fake channels used as group headers by providers, starting with ####
