…ismatch - Add data/cookie_storage to DATA_FILE_GLOBS so --fresh removes it - Catch SystemExit in auth_svc when file_svc._read() fails to decrypt stale cookie_storage; regenerate session key instead of crashing - Add tests: DATA_FILE_GLOBS membership + stale cookie recovery Fixes crash when switching between --insecure and secure mode after PR mitre#3264 introduced persistent session cookies.

Description
Adds server-side input validation for the
technique_namefield inAbilityApiManager._validate_ability_data.Previously,
technique_namewas accepted as an unconstrained string whileidandtacticwere both validated against an alphanumeric allowlist. This inconsistency allowed HTML/script
characters to be stored via
POST /api/v2/abilitiesandPUT /api/v2/abilities/{id},contributing to a stored XSS vulnerability in the Debrief plugin's technique graph.
A regex allowlist (
^[a-zA-Z0-9\s\-_()/.,&:]+$) is applied totechnique_nameon write,rejecting values containing
< > " ' ;while accepting all legitimate ATT&CK technique names.Related to: fix/technique-name-xss in mitre/debrief.
