feat: read "Занятия в Полоцке" as a day's town, show it in all clients

- Parser 14 (server/places.js): "Занятия в Полоцке/Новополоцке/г. Новополоцк" over a day's first row is no longer a lesson but a note of the day for its column (`places`); lessons of that day get `place`. A lesson below the note in the same cell keeps its own subject.
- A town on its own line ("Новополоцк", "г.Новополоцк") or after a room ("246(Новополоцк)") becomes the lesson's `place` and leaves the subject and room. "История Полоцка" is not a town.
- API 14: `place` on lessons and `places` on days of /api/timetable, `place` in the directory. The day notes are shared by the server and the PWA (shared/places.js); the same note in every subgroup reads as the whole group's.
- Android, PWA and iOS: a "Занятия в Полоцке" card above the day's lessons (day pages, calendar, overview, week view, desk stand), "Полоцк" under the date in the week grid, "249Ж · Полоцк" on lesson cards, a "Город" row in details, the town in widgets, tile, reminders and change lists.
- Snapshot lines show the town and the day notes; tests for notes, towns in cells and the API.
