fix: lowercase identifier values in routing form editor

[PeerRich]

What does this PR do?

Lowercases the "Identifier (URL Parameter)" field values in the routing form editor (/routing/form-edit/). This ensures URL parameters are consistently lowercase.

Changes:

• Auto-generated identifiers from labels are now lowercased
• Manual user input in the identifier field is automatically converted to lowercase
• Removed unused @ts-expect-error directives (cleanup)
• Updated E2E tests to use lowercase identifiers to match new behavior

Mandatory Tasks (DO NOT REMOVE)

• I have self-reviewed the code (A decent size PR without self-review might be rejected).
• I have updated the developer docs in /docs if this PR makes changes that would require a documentation change. N/A - no documentation changes needed.
• I confirm automated tests are in place that prove my fix is effective or that my feature works.

How should this be tested?

1. Go to /apps/routing-forms/forms
2. Create a new routing form or edit an existing one
3. Add a new field with a label containing uppercase letters (e.g., "What Is Your Name")
4. Verify the auto-generated identifier is lowercase (e.g., "what-is-your-name")
5. Try manually typing uppercase letters in the identifier field
6. Verify the input is automatically converted to lowercase

Human Review Checklist

• Verify this is the desired behavior for URL parameters
• Consider if existing forms with uppercase identifiers need any migration or if this only affects new/edited fields
• The comparison logic for detecting auto-generated identifiers now compares against lowercase - verify this doesn't cause issues with existing forms
