* security: add nonce CSP mode for inline JavaScript protection
Reworks the content_security_policy_script setting into a three-mode Inline JavaScript Protection dropdown (HTMLX default, Nonce, None) and ports the per-request nonce, strict-dynamic policy, and CSP violation report endpoint from 1.2.x. The stored option key and its default are unchanged, so existing installs keep their current policy byte-for-byte; nonce mode is opt-in.

* security: stage nonce CSP enforcement safely
Add report-only migration, gated enforcement, nonce-aware shared emitters, Linux Docker validation, and operator documentation.\n\nRefs #7703
* security: validate CSP header sources
Reject malformed alternate-source configurations at the CSP boundary, validate fallback report URIs, and remove the obsolete Psalm header-taint baseline entry.\n\nRefs #7705
* chore: drop the composer.json change from this PR
Dependency and manifest changes are a maintainer call and do not belong in
this one.
