feat(web): plainer words for grab, blocked, deck

Three words the operator reads change; nothing underneath does. Waivers
are still written, recorded and served under their existing names, the
`blocked` column and flag keep theirs, and the release deck keeps its
name in DESIGN.md §9.3 and in the code.

- `waive + grab` reads `force grab`, and its accessible name says which
  rule the click relaxes. The `waived` bucket reads `below policy`, and
  so does the verdict chip on its rows — an operator can act on "below
  policy" and cannot act on the name the record keeps.
- A waived import already said what was relaxed for two rules; `size`
  joins them and the fallback names the rule rather than badging it
  `waived`.
- `blocked` reads `no targeted search`, everywhere the flag surfaces.
  §6.3 gives it one effect and a bare toggle hid it: the accessible name
  carries the RSS half at rest, and a note under the controls spells it
  out while the flag is on.
- The season and episode controls are already the #230 search icon; only
  their labels still said "deck". They now say what the click does.

`just ci` passes through the gate: 509 tests, biome, tsc, tokens.

series detail, the episode release view, queues and settings, at 1440
