feat: Add support for minutes in auto resolve feature (#11269)

### Summary

- Converts conversation auto-resolution duration from days to minutes
for more
granular control
- Updates validation to allow values from 10 minutes (minimum) to 999
days (maximum)
- Implements smart messaging to show appropriate time units in activity
messages

###  Changes

- Created migration to convert existing durations from days to minutes
(x1440)
- Updated conversation resolver to use minutes instead of days
- Added dynamic translation key selection based on duration value
- Updated related specs and documentation
- Added support for displaying durations in days, hours, or minutes
based on value

###  Test plan

- Verify account validation accepts new minute-based ranges
- Confirm existing account settings are correctly migrated
- Test auto-resolution works properly with minute values
- Ensure proper time unit display in activity messages
