feat(marketing): project-branded drafts + project badges on the X/video queues (#570)

Item B+C of the video/X per-project targeting spec, plus the
company_goals.company_name field they depend on (migration 075).

- CompanyGoalsService.resolve_product_name is the single fallback chain
  (project name -> charter company_name -> RoboCo); XEngine and
  VideoEngine both call it and their prompt builders are pure functions
  taking product_name — release posts/videos stop hardcoding RoboCo.
- The X and video queue responses carry project_slug/project_name via one
  shared unloaded-guard helper (api/schemas/project_fields.py); both
  panel queues render a shared ProjectBadge so multi-project drafts are
  tellable apart.
- Business -> Goals editor gains the company-name input.
- Fixes a pre-existing test-isolation leak: the company-goals routes test
  commits the charter singleton into the session-scoped test DB and
  polluted later suites; it now deletes the row on teardown.
