Subject: [PATCH 16/21] Address the review on partners, and confirm deletes one
 way
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Findings:

* Partners were exported and displayed but never added to the free-text
  search, unlike every other name-bearing collection. One subquery, mirroring
  contacts.
* Assert\Valid on the partners association raised violations at
  partners[0].name — a path the single text input cannot render, on a form
  autosave never redraws. The transformer now checks the one thing this form
  can get wrong, so the error lands on the field itself.
* The unique index on partner.name made lookup-then-insert a 500 waiting to
  happen, since partners are created inline from the autosaving form. Dropped
  in favour of the UniqueEntity check Contact and Term already rely on: the
  worst a race can now do is leave two rows to merge.
* The migration says what it does.

Delete confirmation was three idioms — onsubmit=confirm(), data-turbo-confirm,
and the new dialog. Now one component, everywhere. Its trigger is no longer a
submit button, so a click landing before Stimulus hydrates does nothing rather
than deleting unguarded.

Subject: [PATCH 17/21] Clamp over-long partner names instead of rejecting them
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A TransformationFailedException desynchronised the form, so autosave —
the initiative form's only save path — returned a bodiless 422 and showed
the generic 'check the required fields' error. Nothing was missing and the
field carried no error, so every later save failed with no way to see why.

Subject: [PATCH 20/21] Trim partner comments

The note on Partner::$name claimed Contact and Term as precedent for
skipping a unique index, but Term carries uniq_term_name_vocabulary while
taking the same lookup-then-insert race, and UniqueEntity only guards the
admin form. Drops a TODO from the delete docblock too.
