Fix currency input regex + migrate to storybook/test v9 (#10)

* fix: tighten currency input regex + migrate to storybook/test v9

- Replace permissive regex with two-stage parse: strip non-numeric,
  then clamp to valid number format (optional leading minus, single
  decimal point). Prevents malformed input like '1.2.3' or '1-2-3'.
- Remove @storybook/test (v8) and @storybook/testing-library,
  migrate imports to storybook/test (v9 path). Eliminates SB9
  compatibility warning.
- All 51 interaction tests pass.

* fix: hoist regex to module scope + sort imports for biome lint

- Extract regex literals to module-level constants (biome/useTopLevelRegex)
- Fix import ordering in story files (biome/organizeImports)
- All 51 tests still passing

* Add changeset for currency input fix (patch)
