- Add formatDateForTitle helper: returns today/tomorrow labels or dd.MM.yyyy
- Switch all search page title builders to use formatDateForTitle; descriptions keep dd.MM.yyyy
- FLIGHT-DETAILS title now uses routeCities (no date) per TZ rows 6-8; adds TITLE-NO-ROUTE fallback for SSR when cities not yet loaded
- buildFlightDetailsSeoFromId accepts optional cityNames param
- Update ru/en i18n TITLE strings to TZ Table 6 format; add TITLE-NO-ROUTE to all 9 locales
- Tests: 32 cases covering today/tomorrow/arbitrary-date branches and routeCities logic
