## What does this PR do?

- Fixes #25116
- Fixes [CAL-6741](https://linear.app/calcom/issue/CAL-6741/make-routing-edit-question-form-less-intrusive-on-how-it-handles-the)

Improves the routing form field identifier auto-fill behavior to generate URL-safe identifiers from labels. Previously, the identifier field simply duplicated the label text. Now it normalizes the input to be URL-friendly.

**Changes:**
- Converts labels to lowercase with hyphens (e.g., "What is your name?" → "what-is-your-name")
- Limits identifiers to the first 5 words (e.g., "What do you work on and how can we help?" → "what-do-you-work-on")
- Updates the Identifier label to clarify it's a URL parameter with an example
- Preserves manual identifier edits when the label changes

## Key Implementation Details

The `normalizeIdentifier` function:
- Strips special characters and replaces them with spaces
- Converts to lowercase
- Splits on whitespace and takes first 5 words
- Joins with hyphens

The auto-fill logic only updates the identifier if:
1. The identifier field is empty, OR
2. The identifier matches the normalized version of the previous label

This preserves manual edits while still providing helpful auto-fill for new fields.

## Mandatory Tasks (DO NOT REMOVE)

- [x] I have self-reviewed the code (A decent size PR without self-review might be rejected).
- [x] I have updated the developer docs in /docs if this PR makes changes that would require a [documentation change](https://cal.com/docs). If N/A, write N/A here and check the checkbox. **N/A** - This is a UI behavior change that doesn't require documentation updates.
- [ ] I confirm automated tests are in place that prove my fix is effective or that my feature works. **Note:** No automated tests were added for this change. Manual testing is recommended.

## How should this be tested?

**Test Cases:**

1. **Basic normalization:**
   - Create a new routing form field
   - Enter label: "What is your name?"
   - Verify identifier auto-fills to: "what-is-your-name"

2. **5-word limit:**
   - Enter label: "What do you work on and how can we help?"
   - Verify identifier becomes: "what-do-you-work-on"

3. **Special characters:**
   - Enter label: "Email (required)!"
   - Verify identifier becomes: "email-required"

4. **Manual edit preservation:**
   - Enter label: "Test Field"
   - Manually change identifier to: "custom-id"
   - Change label to: "New Test Field"
   - Verify identifier stays: "custom-id" (not auto-updated)

5. **Updated label text:**
   - Verify the Identifier field label shows: "Identifier (URL Parameter, i.e.: &what-is-your-name=john-doe)"

**Environment:**
- No special environment variables needed
- Test in the routing forms builder at `/apps/routing-forms/[formId]`

## Important Review Points

⚠️ **No automated tests**: The normalization function and auto-fill behavior lack test coverage. Consider adding unit tests for edge cases.

🔍 **Auto-fill logic**: The identifier only auto-updates if it's empty or matches the previous normalized label. This preserves manual edits but may be surprising to users in some scenarios.

🌍 **Unicode handling**: Non-ASCII characters are replaced with spaces. This may not be ideal for international users with non-English labels.
