Correct Worker name to isamples-data; account_id; route ordering (#121)

Discovered during initial deploy that data.isamples.org was already
served by a Cloudflare Worker named 'isamples-data' (not 'data-isamples-org'
as I'd named the new one). Also found two wrangler.toml issues:

- `routes` appearing after [[r2_buckets]] got TOML-scoped to that table
- No explicit account_id meant non-interactive deploys failed with
  "more than one account available"

Fixes:
- Rename Worker to 'isamples-data' so `wrangler deploy` atomically
  replaces the existing Worker at that name (preserving the route
  binding in one step).
- Add account_id for Raymond.yee@gmail.com's account.
- Move `routes` above [[r2_buckets]] so TOML parses it as a top-level key.
- Update README to document the name choice.

Deployed 2026-04-17, verified: Cache-Control: public, max-age=31536000,
immutable is now returned for isamples_202601_*.parquet files. Range
requests continue to work (206 + Content-Range).
