Multi-checkbox form support

Layer / File(s)	Summary
Field contracts and option parsing backend/src/main/kotlin/hu/bme/sch/cmsch/component/form/FormComponentController.kt, backend/src/main/kotlin/hu/bme/sch/cmsch/component/form/FormElement.kt	Documentation now defines multi-checkbox formats. The enum uses client-side rendering, and option parsing trims comma-separated values.
Client field variant and rendering frontend/src/util/views/form.view.ts, frontend/src/util/core-functions.util.ts, frontend/src/pages/form/components/autoFormField.tsx	The frontend adds the variant, parses submitted and default values, and renders selectable checkbox groups.
Submission normalization and validation frontend/src/pages/form/form.page.tsx, backend/src/main/kotlin/hu/bme/sch/cmsch/component/form/FormMasterFillDashboard.kt, backend/src/main/kotlin/hu/bme/sch/cmsch/component/form/FormService.kt	The frontend submits JSON strings. The backend normalizes values, validates configured options and regex entries, rejects duplicates, and stores valid JSON lists.
Form-editor card management backend/src/main/resources/templates/component/details/form-editor.html	Field cards are generated and managed through DOM elements. Deletion removes and renumbers cards, and help text documents multi-checkbox values.

🟠 Major · Validate each selected value for MULTI_CHECKBOX. · autoFormField.tsx:81

frontend/src/pages/form/components/autoFormField.tsx:81
🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Validate each selected value for MULTI_CHECKBOX.

When formatRegex allows one option, such as ^(lunch|dinner)$, the generic pattern rule at Line 81 receives ["lunch", "dinner"]. RegExp.test converts that array to lunch,dinner and rejects it. The backend validates each list entry at FormService.kt Line 247, so the client blocks a submission that the backend accepts. Exclude MULTI_CHECKBOX from this generic rule and validate each selected value separately, or rely on the backend validation.

MULTI_CHECKBOX arrays, since it tests the serialized whole array rather than
individual selections. Exclude MULTI_CHECKBOX from this rule and validate each
selected value against formatRegex separately, or omit client-side pattern
