Remove all inline JS from admin templates

script-src 'self' blocks inline onclick handlers and <script> blocks.
Migrate all interactive behavior to data-* attributes wired by mcias.js:

- data-toggle-form: accounts, policies, pgcreds create-form buttons
- data-href: audit clickable table rows
- data-tab: policy form tab switching (moved showTab from inline script)
