revert: roll back to 7d854ff (pre-security-review state)

Restores all 27 files changed by the security commit (f8a1310) and later
work back to their 7d854ff state (2026-06-16 18:05), as requested. The
security rewrite regressed map functionality (tabs, inspection editor,
collapsing layers panel) without adding protections the 7d854ff version
did not already have (XSS escaping + IDOR checks were already present).

Done as a forward commit (no history rewrite / force-push) so f8a1310,
a24c8a2 and the merge remain in history and are fully recoverable.
