* Fix/employees page salary display logic and labels * feat: add salary_worked_days table and related functionality - Implemented the salary_worked_days table to track per-day worked hours for hourly employees. - Established row-level security (RLS) policies to ensure tenant isolation for salary_worked_days. - Created unique index on (employee_id, work_date) to enforce uniqueness. - Added trigger to enforce a 24-hour cap across worked and absence days for the same employee and date. - Developed tests to validate RLS, uniqueness, and 24-hour cap logic. * Fix: update hourly_salary calculation and refresh logic in salary run processing

-- Migration: salary_worked_days — per-day worked hours for hourly employees
|
||
--
|
||
-- Why this exists: hourly employees (timanställd) need per-day hour tracking
|
||
-- so payroll can derive base salary as `hourly_rate × Σ hours`. The previous
|
||
-- model relied on a single nullable `salary_run_employees.hours_worked`
|
||
-- column, but had no UI to set it after the employee was added to a run.
|
||
--
|
||
-- Mirrors salary_absence_days deliberately: same calendar UX, same RLS shape,
|
||
-- same per-day granularity. Worked time and absence time are separate domain
|
||
-- concepts (presence vs frånvaro) so they live in separate tables — combining
|
||
-- them via an enum would pollute every absence-side query (AGI Frånvarouppgift,
|
||
-- högriskskydd lookups, sjuklöneperiod derivation).
|
||
--
|
||
-- Half-day mixing is allowed: an employee can have 4h worked + 4h sick on the
|
||
-- same date. The 24-hour cap across both tables is enforced by the trigger
|
||
-- introduced in 20260512120100_worked_days_absence_conflict_trigger.sql.
