SeaORM: items and read state

The item list, its counts, filters, sorts and search, positions, pins and
mark-all-read move to SeaORM, as SQL written for both databases:

- Parameters are gathered as the SQL is written (Args), so only what a
  statement uses is bound. rusqlite needed every one mentioned, hence the old
  `?1 IS NULL` and `?2 = ''`; Postgres refuses a parameter it cannot type.
- Yes/no columns are tested as booleans (NOT coalesce(s.read, false)) and
  written as true, not 1; SQLite reads true and false as 1 and 0.
- The last tiebreak of the sort is the guid, not SQLite's rowid, which Postgres
  lacks. Only items with the same date change places.
- set_position names entry_state.duration beside excluded.duration.
- The status callback on the control socket returns a future, as the counts
  are now a query.

Checked on a copy of production against the live server: 42 of 48 lists
identical; the other six differ only in how ties fall, or because the test
daemon cleared paths to files this machine does not have. Run on the same file,
every filter's count matches the old SQL exactly.
