feat(campaigns/detail): edit draft params + jump to template editor

Two new buttons on the campaign detail page header — both visible only
when campaign.status === 'draft' to keep operators from accidentally
mutating a campaign mid-send.

"Éditer les paramètres" → q-dialog with:
- name (internal)
- subject (the email Subject: line)
- from (sender)
- amount displayed in the body (overrides per-recipient default)
- commitment_months
- expiry text
- template_fr / template_en dropdowns (refresh on popup-show so newly
  created templates show up without a page reload)

Saves via the existing PATCH /campaigns/:id, which merges into
params. A live load() refresh updates the Confirmation recap and any
visible counters.

"Éditer le template" → opens the Unlayer editor in a new tab on the
campaign's configured template_fr (most TARGO customers FR). For
campaign-specific tweaks the dialog tells the operator to create a
variant template (+ Nouveau) and select it here.

Addresses the gap a user hit on a reminder draft — they wanted to add
a condition to the body before launching but had no edit affordance
on the detail page.
