Atlassian Cloud: remove product access to free license seat

[LuD1161]

Goal: Ensure the user doesn’t consume Jira/Confluence seats.
Tasks:

• Research how Atlassian allocates seats (product access groups vs per-user toggles).

• Identify API(s) to remove product access.

• Input: email or account_id

• Steps: resolve account → remove from access groups → deactivate.

• Verify seat released via product access listing.

• Emit audit JSON (products removed, groups changed).
  Acceptance:

• Dry-run mode.

• Idempotent.

• Unit tests for “no product access” case.
