provider dashboard redesign: copy-URL/OpEx/Fund icons, OpEx Balance card, councils list, Live/Range dashboard with fade in/out

[AquiGorka]

Summary

Full redesign of `/provider/:pk`.

• Header: back arrow + name on the left; copy-provider-URL, copy-OpEx-address, and Fund (Freighter) icon buttons on the right.
• "OpEx Balance" card (label + value stacked).
• Councils list (3-up grid) — each card shows name + merged jurisdiction flags + assets; click an asset chip to copy the channel id.
• Dashboard with 5 columns: Deposit / Mempool / Submitted / Verified / Withdrawn. UTXOs column dropped (the same info lives inside the per-tx detail card).
• Two modes, controlled by tabs:
  • Live — events fade in (double-rAF) and stay 30s before fading out. Items stay in their column; no cross-column "movement". Live tab is disabled when the WS isn't open; on disconnect the view auto-flips to Range.
  • Range — date pickers + Search. Calls the new `/dashboard/transactions` list endpoint and dedupes each tx to its terminal column.
• Tx detail card with a close button; auto-clears on mode switch.
• API client adds getTreasury(pp), getUtxos, getTransactionDetail, listTransactions. PpInfo and events-client know the new shapes/kinds.
• Counts badge in every column header.

Note: branch carries a chore: bump version 0.2.22 → 0.2.23 you wanted dropped (preserve-history); flag remaining for cleanup before merge if desired.

Test plan

• deno task fmt --check, lint, check, build, test pass
• End-to-end via local-dev: send-loop fills the columns, items fade after 30s, Range search returns historical data, click-into-tx shows detail, Fund icon opens Freighter
