restore: bring back f8a1310 (security review) state

Restores all files to the f8a1310 security-review snapshot as requested,
plus the 2 boot-critical fixes from a24c8a2 (config/session.php env()
instead of app()->environment(), and removal of the duplicate $activeTab
in ProjectMap.php) so the application actually boots.

Forward commit, no history rewrite. The 7d854ff state remains in history.
