WIP: Add a comments sidebar & associate comments to specific objects

[wes-otf]

Closes #4871. Adds the ability to comment on objects like Project Forms, SOWs, Reports & Invoices via a "mini" comment form in the detail view sidebar for said objects.

This PR also covers a few related yet adjacent things:

• Formatting fixes to normalize the detail views between Project Forms, SOWs, Reports & Invoices.
• New events for "creating" (first edit) and editing of the Project Forms/SOWs
• Tailwind formatting (ie. max-w-[60rem] → max-w-240)

TODO:

• Rebase
• Add unit tests
• Make status updates to PF/SOW reactive like they are for Invoices
• Associate status updates (ie. approvals) to the ProjectFormPointer instead of the project so they show in the Status & Activity section
• Unify the CommentForm more to be able to the used for both the comments tab and the comment sidebar
• Visibility - does it need to be a field on the comment sidebar?
