When all providers for a certain action are disabled, or if providers
are enabled but all individual actions of a type are disabled, then
a warning is shown on the placement admin settings page for actions
that have no providers available.
Also the text editor placement will not show the option to generate
images or text if there are no actions available.
- Quiz is setting the text editor id in this format: `#q2:1_answer`.
This will break the querySelector(). We need to update the code to
escape those colons.
- Generate AI image requires users to have the capability to upload files.
A new extra condition is added to verify this one.
To make the plugin name a bit more generic, we renamed as below
- Shortname: `aiplacement_tinymce` -> `aiplacement_editor`
- Fullname: `TinyMCE Editor Placement` -> HTML Text Editor Placement
Initial AI placement plugin for the TinyMCE editor.
It includes a TinyMCE plugin and the AI placement plugin.
It supports both text and image generation.
Originally implemented in MDL-80891
