refactor: extract inline JS into app/ modules, remove dead overtype-webcomponent

- Remove overtype-webcomponent.min.js (zero references)
- Extract copyLogContent + fallbackCopy + HTMX tab-updater → app/admin-logs.js
  (removes duplicate from both system.php and parametres.php)
- Extract copyUrl → app/clipboard.js (shared by acces.php)
- Extract tag/language pill-search logic → app/pill-search.js
  Generalized with data-pill-search attributes, auto-inits via
  DOMContentLoaded + htmx:afterSwap
- Extract access-request form handler → app/access-request.js
  (was inline in templates/public/tfe.php)

Files created: admin-logs.js, clipboard.js, pill-search.js, access-request.js
Files modified: 9 templates/controllers to drop inline scripts and
  reference external JS files

app/templates/admin/parametres.php
