- Fixes SLA breach computation to respect the "Only during business
hours" setting
- Backend now pre-computes SLA deadlines, simplifying frontend logic
## How it works
Before: SLA deadlines were calculated using wall-clock time, ignoring
business hours.
After: When an SLA policy has "Only during business hours" enabled and
the inbox has working hours configured, the deadline is calculated by
adding threshold time only during business hours.
**How you check if a conversation has a SLA hit or miss?**

**Example:**
- Conversation created: Friday 4:30 PM
- FRT threshold: 1 hour
- Business hours: Mon-Fri 9 AM - 5 PM
| | Breach time |
|--|--|
| Before | Friday 5:30 PM |
| After | Monday 9:30 AM |
## Test plan
- [x] Create an SLA policy with "Only during business hours" enabled
- [x] Configure inbox with business hours (e.g., Mon-Fri 9-5)
- [x] Conversation created during business hours
- Create a conversation on Wednesday 10:00 AM UTC
- Expected: FRT deadline shows Wednesday 12:00 PM UTC (2 business hours
later)
- [x] Conversation created before business hours
- Create a conversation on Wednesday 7:00 AM UTC
- Expected: FRT deadline shows Wednesday 11:00 AM UTC (counting starts
at 9 AM)
- [x] Conversation created after business hours
- Create a conversation on Wednesday 6:00 PM UTC
- Expected: FRT deadline shows Thursday 11:00 AM UTC (counting starts
next day 9 AM)
- [x] Conversation created on weekend
- Create a conversation on Saturday 10:00 AM UTC
- Expected: FRT deadline shows Monday 11:00 AM UTC (skips weekend)
- [x] Threshold spans weekend
- Create a conversation on Friday 4:00 PM UTC with 2-hour FRT
- Expected: FRT deadline shows Monday 10:00 AM UTC (1h Friday + 1h
Monday)
- [x] SLA without business hours
- Create an SLA policy with only_during_business_hours: false
- Create a conversation on Friday 4:00 PM UTC with 2-hour FRT
- Expected: FRT deadline shows Friday 6:00 PM UTC (wall-clock time)
- [x] All Day marked as closed_all_day
- Create a conversation on Tuesday 4:00 PM UTC with 2-hour FRT
- Expected: FRT deadline shows Thursday 10:00 AM UTC
- [x] All Day marked as open_all_day
- Create a conversation on Saturday 10:00 AM UTC with 2-hour FRT
- Expected: FRT deadline shows Saturday 12:00 PM UTC
- [x] UI displays correct countdown
- Verify conversation card shows correct SLA timer
- Verify timer shows flame icon when breached
- Verify timer shows alarm icon when within threshold
- Time updates automatically when time passes
- [x] Verify the breach with a different timezone than your local
timezone
