2g rework: address DA findings on type recovery + engine routing + UI

Browse Source 
Three DA critiques from the Phase-2 verification flagged real gaps;
this commit closes them.

1. Type recovery row-independence (critique #1). The all-10-types
   test left col_blob NULL because the DSL Value enum has no Blob
   variant. The DA flagged this as a potential row-dependence gap.
   Added `database_run_select_type_recovery_works_on_empty_table`
   that proves column-origin metadata works on Text AND Blob
   columns with zero rows, pinning the invariant. The all-types
   test now carries an explicit comment referencing it.

2. Engine.* pattern matching against real SQLite output (critique
   #2). The pre-rework tests fed `translate_generic` hand-coded
   strings; never verified that the pinned SQLite version actually
   produces those wordings. Added three engine-routing tests in
   `tests/sql_select.rs` that produce real engine errors via
   `run_select` and assert catalog routing. Aggregate-in-WHERE
   confirms end-to-end. GROUP-BY-required and scalar-subquery
   are SQLite-permissive (no real error on the natural triggers),
   so those tests verify the matcher doesn't false-positive on
   benign queries + that synthetic messages route correctly.

3. Manual TUI verification (critique #3) surfaced an additional
   gap: `App::input_validity_verdict()` was hard-coded silent in
   Advanced mode, so SQL predicate warnings emitted but never
   reached the [WRN] indicator. Wired the verdict through to the
   active effective mode; updated two pre-existing tests that
   pinned the now-superseded "silent in Advanced" behavior; added
   one new test confirming a SQL `LIKE`-on-numeric warning fires
   the indicator. Launched the TUI, typed a representative
   warning-triggering SELECT, confirmed SELECT/FROM/WHERE/LIKE
   highlight as keyword colour AND the [WRN] indicator appears.

Test totals: 1441 → 1446 passing (+5). Clippy clean.
