Case Files Professional 4.0.0 - Development Consolidation Stage 3

Scope: app/views.php only.
- Preserves Stage 1 Internal Notes workspace navigation and all other existing links.
- Gives case workspace tabs distinct context-appropriate SVG icons.
- Does not modify roles, backend, schema, version, evidence, or GPS logic.

INSTALL: ONLY after Stage 1 and Stage 2, on corfuconsulting.com development.
Backup app/views.php, then extract at the site webroot preserving app/views.php.
Do NOT apply to GIB production or Commercial test yet.

VERIFICATION: PHP lint and ZIP integrity checked; no browser/live tests performed.

AUDIT: Current development snapshot already includes a closure override in app/cases.php and case.php, and the evidence detail header already places one disposition/custody button adjacent to Delete. Those are NOT reimplemented here; they require live behavioral validation.
