The dream journal's table (ADR 0038, D14): `dream`, in the sync engine's
database, a row a dream, its content sealed on the device (key ID,
payload, nonce), so the instance sees only that a dream exists, its size
and when it changed. The same rules as the sittings: the sync engine's
connector refuses a call without a session, each row lives in its
person's space, and deleting the person deletes their dreams with it
(the deletion test now writes and counts a dream too, and leaves
another person's).
The migration `20261103130213716-dreams`:
- `CREATE OR REPLACE FUNCTION gen_random_uuid_v7()`: the generator
repeats the UUID v7 function every migration; replacing it with the
same body changes nothing.
- `CREATE TABLE "dream"`: `id` a UUID v7 by default, `spaceId` the
person's sync space, `keyId` the key it is sealed with, `payload` the
sealed bytes (not null), `nonce` the sealing's nonce.
- `CREATE INDEX "dream_space_idx"` on `spaceId`, so deleting a space
finds its dreams without scanning the table.
- The foreign key from `spaceId` to `offline_sync_spaces("id")` with
`ON DELETE CASCADE`: deleting the space deletes its dreams.
- The version rows of every module in `serverpod_migrations`.
A new, empty table: nothing existing changes and no data moves.
