fix: remove unused dependencies

[DerekRoberts]

This PR removes unused dependencies identified by Knip and adds documentation for reporting false positives upstream.

Changes

Removed Dependencies

Frontend:

• @faker-js/faker - Not used in codebase
• @tanstack/react-router-devtools - Not imported or used
• history - Not used (TanStack Router has its own history implementation)

Backend:

• source-map-support - Not imported or used
• ts-loader - Not used (project uses SWC via nest-cli.json)
• ts-node - Not used in scripts
• tsconfig-paths - Not used (using NodeNext module resolution)

Documentation Added

Added a new "Dependency Scanning with Knip" section to the README that includes:

• How to handle unused dependencies
• Process for reporting false positives upstream to bcgov/action-test-and-analyse
• Example PR format for upstream repository
• Common false positive patterns

Configuration

Note: Team-specific knip.config.ts files are not used. All Knip configuration is managed centrally in the upstream bcgov/action-test-and-analyse repository. Teams should report false positives upstream rather than maintaining local config files.

False Positive: @testing-library/user-event

@testing-library/user-event was flagged but is a false positive. It's exported from test-utils.tsx for use in tests but not directly imported yet. This should be reported upstream to bcgov/action-test-and-analyse for addition to .knip.json if needed (see README for process).
