fix: address Copilot PR review

- .mcp.json: playwright-test config path apps/web -> apps/tanstack
  (apps/web removed earlier in dev, MCP server couldn't start)
- AGENTS.md: pnpm format command description matches the new
  `biome check --write .` script; add `pnpm ci` line
- globals.css: restore !important on Radix scroll-lock overrides
  (biome --unsafe stripped them but they're semantically required to
  override Radix's inline styles); silence noImportantStyles via
  biome-ignore-all
- server.test.ts: rename misleading 'GET /rpc/planet/list' (the
  helper sends POST) to 'POST /rpc/planet/list'

Skipped Copilot's suggestion to scope pnpm filters as
`@nn-stack/tanstack` — pnpm matches unscoped names against the
package.json `name` suffix, the current `--filter tanstack` works.
