Issue 2: API Support for Anonymous Posts

Dependencies: Issue 1 (schema)
Milestone: Sprint 1
Description:

• Update API to allow creating posts with isAnonymous = true.
• When fetching posts, hide author info if isAnonymous is true (except for staff endpoints).
• Ensure editing/quoting posts respects isAnonymous.

Acceptance Criteria:

• Posting with isAnonymous = true hides author for regular users.
• Staff-only API can reveal true author.
• Attempting to override anonymity via API fails unless staff.
