feat(meditate): the dream journal, a fourth tab, Today's morning card

ADR 0038, D14. A dream (`Dream`) holds the night it belongs to (the
morning's date, today's by default), an optional title, its text, the
marks lucid, nightmare and recurring, a clarity of 1 to 5, the mood on
waking and free labels, and when it was written; a row each in `dream`,
sealed for its row with the person's key as the sittings
(`DreamRepository` on `SealedRows`, `SyncDreamGateway`), followed by
`JournalCubit` for every screen.

- The Journal, between Explore and Profile: dreams by month, the
  newest first, searched over title, text and labels as Explore
  searches, filtered by marks, `+` above the bar; empty, it says that
  entries are sealed on the device before they sync.
- A dream's screen over the tabs: a new one with its text first and
  focused, the rest folded below; a kept one to read, with Edit and
  Delete (asked first); leaving one written but not saved asks first.
- Today, from 4 to 12 o'clock while last night has no dream, a gentle
  card leading to a new one; Settings' Journal card switches it off
  (`dreamPrompt` in the sealed settings, schema 1 kept).
- Profile's Practice: this month's dreams and the lucid ones, once the
  journal holds one.
- English and German texts; What's new 0.1.0 names the journal; the
  account's deletion says it takes the dreams too.
