Boost: Re-activating the plugin doesn't run modules activation

[dilirity]

If a user were to enable Concat JS, the module would setup some events. If the user were to then disable boost (they might be trying several performance plugins to compare), Boost will run a cleanup of the events. If they were to activate Boost again, events would not be scheduled again, as that only happens when toggling the module.

Deliverable

Ideally we want to run "activate" on all modules that are active when boost is reactivated (or something similar).

OpenAI suggested the following labels for this issue:

• [Feature Group] Content Management: The issue relates to how content management plugins like Boost handle module activations and interactions with other features.
• [Boost Feature] Setup Prompt: The title and body indicate a need for better initialization of modules when the Boost plugin is activated, aligning with setup functionality.
• [Feature] Concat: The issue specifically mentions 'Concat JS', which indicates a concern with the Concat feature and its integration when Boost is reactivated.

This issue could use some more labels, to help prioritize and categorize our work. Could you please add at least a [Type], a [Feature], and a [Pri] label?
