Improve template field guidance, compact editor UI, and language coverage

[anderson-camacho]

What changed

• added template field support metadata and editor guidance so unsupported fields are clearly identified per template
• updated multiple signature templates to actually render more of the available data, including pronouns, department, address, phone, logo, and photo where appropriate
• improved the compact editor experience with side drawers, sticky close controls, tighter layout alignment, and cleaner spacing across the form
• compacted unsupported-field messaging into inline pills and disabled inputs that a selected template does not use
• refined mobile and narrow-column layouts for workspace meta controls, appearance controls, and social network cards
• expanded locale coverage with additional important languages and verified localized routes

Why

The editor had several areas where controls looked visually misaligned or allowed input for data that a template would ignore. This change makes the compact editing flow clearer, tighter, and more consistent.

Impact

• users get immediate feedback when a field will not be shown by the active template
• unsupported fields no longer invite unnecessary typing
• the compact editor feels more polished on narrow layouts
• social button editing is easier to scan and use in constrained widths
• more languages are available from the locale switcher

Validation

• npm run check
• npm run lint
• npm run test:unit
• npm run build
• npm run test:e2e -- tests/e2e/generator.spec.ts
