fix(frontend): key geo entries by page position and clear test-suite noise

Zod 4: use the `error` param instead of the deprecated `message`.
lint:deprecated missed these because tsgolint's no-deprecated does not
resolve object-literal properties on a `string | Params` union.

Geodata: key geo entry rows by page position. antd deprecates rowKey's
index argument, and kind:value repeats within a page because the reader
drops domain attributes (22 pairs in geosite_IR.dat, 108 in geosite_RU).

Nord/PIA: the "All cities/regions" option used a null value, which antd
warns on. Map it through a sentinel at the Select boundary so form state
stays null, with tests that fail when the sentinel is not mapped back.

Tests:
- Run the oxlint guard through node; .bin/oxlint is a sh shim Windows
  cannot spawn, and the swallowed error left both guard cases vacuous.
- Start unit workers with --no-experimental-webstorage; msw's localStorage
  probe made Node 25+ warn once per forked worker.
- Set IS_REACT_ACT_ENVIRONMENT, which RTL never sets with globals: false,
  and settle the async updates it exposed inside act(). The row-cells
  memo test now fails when memo is removed.
- Disable antd's click wave in Storybook; it re-rendered inside the next
  story's act() and tripped "not configured to support act".
- Assert InboundFormModal's validation log instead of leaking it, and
  give the rule-form test a well-formed clients/list response.
