Audit details page structure + mini-list + day tabs per TZ 4.1.15.1-3 + 4.1.16.1-3

- FlightsMiniListItem: SVO/VKO airport names rendered as role=link spans that open external sites in a new tab (R19, R20) — avoids <a> nesting inside Link - ScheduleDetailsPage: wire FlightsMiniList into contentLeft and DayTabs into stickyContent (schedule window [-1, +330]) per §4.1.16.1 R2/R3 and §4.1.16.3 R22 - Add navigation handler for schedule day-tab clicks (simple date URL swap; full §4.1.16.3.1 re-search algorithm is deferred) - Tests: 72 tests across four files covering R12/R13/R16/R17/R22 (mini-list), R23/R27/R28 (day-tabs), R3/R5/R6/R7 (page structure), R2/R4/R22 (schedule)
