fix: move meeting management items from base menu Documents tab to Meetings tab (fixes #3897 and #4005)

[Spectre17]

Rearranges elements of the optional Manage block in Documents so that they appear in Meetings instead. This is for things like "xxxx wg meetings". Also, put role restrictions around whether "Request a session" and "Request an interim meeting" appear under the Meetings tab.

The role based if clauses here do not match real needs (many other group types use interims for example). Lets talk about using leveraging existing utilities to decide when to offer links instead.

The list of roles I used was based on what was being enforced in the code itself. I just added the role-based restriction to the HTML so that users who were going to trip the code restrictions instead hit HTML restrictions first. Two notes:

1. I'm happy to change the restrictions to a different set or use an existing utility if it can be incorporated into the HTML template.

2. That part of the merge request is not critical to fixing the issue in any case - it was a secondary thing I hit while in that HTML files, so we could break it out to a separate pull request and allow the main fix to be incorporated without being tied to work on the restrictions.
