feat(oxibadge): add timesheet review and export screen

Add the month-review screen shown after records/employees load: an
editable per-employee timesheet table with issue/rounding detection,
bulk fixes (reorder stacked punches, add lunch break, round to step),
and an export flow (single employee or all) wired to a new Rust
export_timesheet command. Split into focused components under
review/ instead of one large file, with shared i18n keys and a new
export_timesheet IPC command.
