feat(web): honest sparse-state and queue copy

Make the sparse reality legible instead of implying abundance or imminence
(UX review A1-A4, A6):

- Empty-connected state drops the impossible "Run `tapir run`" instruction
  (no shell for web users; discovery is in-process since ADR-018) for a
  passive "summaries appear gradually, check back later".
- Pipeline bar reframes counts by what the user can do: "N ready · M in queue
  · K no captions" (was "summarized / fetching soon / pending").
- A one-line note explains captions are fetched slowly on purpose to respect
  YouTube's limits — turning confusing emptiness into intentional design.
- Card state for throttled videos reads "In queue", not "Fetching soon…"
  (256 items behind a per-IP gate are not all imminent — ADR-014).
- Quiet nudge button drops the over-promising "now": "Summarize", not
  "Summarize now". On click the card still honestly becomes "Queued".
- Queued card says "summarizing shortly", not "waiting for the next run"
  (no scheduler jargon).

Pure copy/label — no logic, DB, or fetch-rate change. The rate gate is
untouched; scarcity is surfaced, never engineered around.
