Fix edit form: is_published reset, contact decoupling, note label, author name case

- Fix #1: Add is_published to getThesisRawFields() SELECT so the publish
  checkbox stays checked when editing an already-published TFE.
- Fix #2: Rename 'Note contextuelle' → 'Note contextuelle relative à
  soutenance' in all templates and StudentEmail.
- Fix #3: Update findOrCreateAuthor to also UPDATE the author name when
  a record is found by name (fixes inability to capitalise names).
- Fix #4/#5: Decouple contact_interne (private author email) from
  contact_visible (public contact on TFE page). Add migration 037 to
  add contact_visible TEXT column to theses table and rebuild
  v_theses_full view. Update all controllers, templates, and DB methods
  to treat them independently.
- Fix #6: Investigated libre→interne restriction — no code barrier
  found; likely resolved by is_published fix.
