hzc-8010: field playground consistency (Text/Autocomplete/CheckableSelect)

[pawelklasa]

Consistency pass on the input/dropdown field family, matching the cleanup shipped in PRs 637-640.

What

• Playground controls: replaced leaky exclude lists with curated include whitelists on TextField, AutocompleteField and CheckableSelectField so the Controls panel only shows meaningful, user-facing props.
• Do & Don't: added a real Do/Don't section (live story + Guidelines-tab wiring) to AutocompleteField and CheckableSelectField, which were missing one. TextField already had a Do/Don't.

Out of scope

• TimeField still uses the legacy story format (no Playground/docs tabs); it needs its own redesign ticket and will be handled separately.

Validation

• tsc -p tsconfig.build.json --noEmit clean
• eslint clean on changed stories
• jest: 39 tests pass across TextField/Autocomplete/CheckableSelect
• Verified both new Do/Don't stories render with all four pairs in Storybook

Note: branch uses placeholder ticket hzc-8010 — rename if a real ticket exists.
