Fix security vulnerabilities in npm dependencies (#11815)

* Update package dependencies: remove unused 'picomatch' and 'minimatch' modules from package-lock.json, and add specific versions for 'picomatch', 'minimatch', 'path-to-regexp', and 'serialize-javascript' in package.json.

* Upgrade nx and @nx/workspace to fix minimatch vulnerabilities

- Upgrade nx from 22.4.1 to 22.6.3
- Upgrade @nx/workspace from 22.4.5 to 22.6.3
- Remove minimatch override to maintain Karma compatibility

This resolves the high severity minimatch vulnerabilities while
keeping tests functional.

* Refactor nx.json: Consolidate sharedGlobals array and add analytics flag

- Merged multiple lines in the sharedGlobals array for better readability.
- Added an analytics flag set to false for configuration.

* Update package dependencies: bump @nx packages to version 22.6.5 [ci:force]

* Add test specifications for feature flags and user initial pipe [ci:force]

- Introduced new selectors for feature flag components in `features.directive.spec.ts` and `not-features.directive.spec.ts`.
- Added an injectable sanitizer class in `user-initial.pipe.spec.ts` to enhance testing capabilities.
- Created a new log file `out.txt` to capture Karma test execution details and warnings.
