fix(backend): address PR review round 2 — TDD for 3 bugs + docstring fix

Bugs found by sentry, coderabbit, and Pwuts. Each had a failing xfail
test written first, then fixed, then xfail removed.

Fixes:
1. update_org_member: bare next() replaced with next(..., None) + NotFoundError
   — prevents StopIteration crash if member disappears concurrently (sentry)
2. add_workspace_member: now verifies workspace belongs to the claimed org
   — prevents adding members to workspaces in other orgs (coderabbit)
3. test_assign_seat: fixed to assert requested seat type not mock default (coderabbit)
4. Docstring format: RST 'Usage::' blocks replaced with plain 'Example::'
   to match codebase style (Pwuts)

3 new tests + 3 existing tests updated.
Total: 127 route tests + 15 credit tests passing.
