feat(communities): allow local users to create new communities

[McPringle]

User Story

As a logged-in local user,
I want to create a new community,
so that I can build and manage a group for shared interests or activities.

---

Acceptance Criteria

• Permissions

  • Only users with account type Local and role User can create new communities.
  • The new community creation page /communities/new can only be accessed by logged-in local users.

• Navigation

  • The avatar menu is extended with a new menu item for creating a community.
  • Clicking the menu item redirects the user to /communities/new.

• Community Creation Form

  • The form on /communities/new includes the following input fields:
    • Profile: required; must be unique within the instance; contains only the local part, without a server name.
    • Name: required and limited to a maximum of 255 characters.
    • Description: optional and may contain Markdown formatting.
  • Adding a community image is not part of this implementation and will be handled in a separate issue.
  • Submitting the form creates a new community.

• Post-Creation Behavior

  • The user who created the community is automatically added as a member with the role Owner.
  • After creation, the user is redirected to the detail page of the new community.

• Testing

  • Manual testing is performed successfully on both desktop and mobile devices.
  • Full automated test coverage is implemented for the added code.
  • All automated tests pass.

Hi @McPringle. Can you please provide some clarification on the following?

• For the Profile field, should the user be able to enter any text up to 255 characters? The backend should be checking if the value is a duplicate by cross-checking with the entries in the database, but I just want to know if there's any defined format.
• For the Description field, should we add any dependency to check if the user have entered any markdown? Or should we just leave it up to the users?
• Lastly, do you want an enum to be created for the Member role? If not, I can just put in "OWNER" in all caps for now, so that you may add your own later down the line.

Please let me know if I'm missing anything here. I'm close toward wrapping up the entire flow.
