Add warning callout for schedule exception deletion

[harsh04044]

Is your feature request related to a problem? Please describe.

When deleting a schedule exception, the confirmation dialog only warns that the action is permanent. It doesn't mention that removing the exception may affect appointments that were cancelled when the exception was created. This can lead to confusion if users later need to reschedule those appointments.

I noticed a TODO comment in the code (lines 170-176 of src/pages/Scheduling/ScheduleExceptions.tsx) indicating this warning was planned but not implemented. The commented code shows the intended warning callout.

Describe the solution you'd like

Add a warning callout below each schedule exception item that informs users about potential appointment impacts. The callout should:

• Use the existing Callout component with a warning variant
• Display below the exception details and above/below the Remove button
• Show a clear message about potential appointment impacts
• Be visually distinct (warning styling) to draw attention
• Be consistent with existing UI patterns

The implementation should uncomment and complete the TODO block, using the existing Callout component from @/CAREUI/display/Callout and appropriate translation keys for internationalization.

Describe alternatives you've considered

1. Adding the warning only in the delete confirmation dialog - Less visible; users might miss it before clicking delete
2. Showing a tooltip on hover - Too subtle for important information
3. Adding a separate Impact section - More complex; a simple callout is sufficient
4. Only showing the warning if appointments were actually cancelled - Requires backend changes; a general warning is simpler and still valuable

The callout approach balances visibility and simplicity without requiring backend changes.

Additional context

• File: src/pages/Scheduling/ScheduleExceptions.tsx
• Lines 170-176 contain the commented TODO block with the intended implementation
• The Callout component is already available at @/CAREUI/display/Callout
• The warning should appear for all exceptions, providing general awareness about potential impacts

The commented code shows:

• TODO comment indicating this feature was planned
• A div wrapper with padding classes
• Callout component with warning variant and Warning badge
• Placeholder text about cancelled appointments that needs to be replaced with proper translation

Screenshots:

• Current state: Exception list shows no warning callout

• Expected state: Each exception should display a warning callout below the exception details

Describe your solution clearly:

Hey, @Jacobjeevan @rithviknishad @abhimanyurajeesh
I'll implement the warning callout by uncommenting the existing TODO block in ScheduleExceptions.tsx and completing it with proper translations. The solution involves:

1. Importing the Callout component
2. Uncommenting and updating the TODO block to use translation keys
3. Adding the translation key to en.json

This is a simple frontend change using existing components. The warning will appear below each exception item to inform users about potential appointment impacts.

Expected Timeline:

• End date: PR is ready will raise after assignment

Additional Context:
The TODO comment and commented code already exist, indicating this was planned. The Callout component is available in the codebase.
