fix: disable booking actions for cancelled/rejected/past bookings

[eeshm]

What does this PR do?

Fixes inconsistent disabled state for booking actions. Several actions (Edit location , Add Guests, Reroute, Reassign) were hardcoded to disabled: false, allowing users to see enabled buttons on cancelled, rejected, or past bookings.

Users could see enabled "Edit Location" or "Add Guests" buttons on bookings that were already cancelled/rejected/past, which doesn't make sense functionally.

• Fixes #XXXX (GitHub issue number)
• Fixes CAL-XXXX (Linear issue number - should be visible at the bottom of the GitHub issue description)

Changes -

• change_location, add_members, reroute, reassign now use isActionDisabled() instead of hardcoded disabled: false
• cancel action now properly checks for isCancelled and isRejected states
• reschedule and reschedule_request now checks for isCancelled and isRejected states

We need to add automated tests to verify this functionality.
