feat(broadcasts) B: list rates, detail funnel + CSV, save-as-draft

UI polish for the Broadcasts feature. Stacked on PR A (correctness).

List page /broadcasts
- Replaces raw Sent/Delivered/Read/Failed columns with Delivery Rate +
  Read Rate cells (percent + inline mini progress bar). Raw counts
  still available on the detail page.
- Sending badge gets a live-looking pulsing dot.
- Indeterminate top-of-page progress bar appears while any broadcast
  has status='sending'. Page polls the broadcasts table every 5 s
  while that condition holds, and stops polling otherwise.
- Mobile: table wrapped in overflow-x-auto.

Detail page /broadcasts/[id]
- Adds a Replied stat card (was missing). Final grid: Total / Sent /
  Delivered / Read / Replied / Failed — 6 cards on desktop, 2 on
  mobile. Color spectrum matches the spec's funnel gradient.
- Pure-CSS horizontal funnel chart: Sent → Delivered → Read → Replied
  with decreasing widths in emerald → teal → blue → indigo. Each bar
  shows its absolute value and percent of Sent.
- Status filter dropdown above the recipients table. Filters
  client-side; header reflects filtered / total.
- "Export CSV" downloads all recipients with status + every milestone
  timestamp + error_message. RFC-4180 quoting.
- Recipients table gains Delivered / Read timestamp columns so the
  CSV columns are also visible at a glance.

Wizard Step 4
- Save as Draft button next to Send Broadcast. Persists a broadcasts
  row with status='draft' and zero recipients — enough for the user
  to recognize the draft in the list. Full resume-into-wizard is a
  future follow-up.
- Confirmation modal before send was already in place; kept as-is.
