feat: data table improvements — SLA column, pagination, column resize, ordinal dates

- Call Recordings: pagination (15/page), column toggle, sortable SLA/duration/date, ordinal dates, SSE refresh
- Missed Calls: full rewrite matching data table pattern (pagination, column toggle, sort, SLA from entity)
- Call History: SLA column from entity field
- Table component: ResizableTableContainer + ColumnResizer for all tables
- Date formatting: formatDateOrdinal utility (1st April, 2nd March, etc.)
- SLA reads from platform call.sla field (seeded for 200 records)
- AI button long-press triggers OTP-gated cache clear for re-analysis
