Module form 

Admin-new form engine.

Turn a FormConfig of FieldConfigs into drawer-based form HTML. Every input type routes through a dedicated renderer that uses only classnames present in the approved components.css — no new classes, no new styles, no JS, no filesystem, no DB.

The ForeignKey rule is load-bearing: FK fields always render as a <select> populated from FieldConfig::options. Raw numeric row ids are never presented to the admin user; the caller resolves (value, label) pairs upstream and passes human-readable labels in.

UI-level validation lives here too: validate_form walks the fields, applies a small set of basic rules (required / email / number), and writes any failure into FieldConfig::error. The renderers add class="invalid" to the input and append a .field-error block below — both classes are referenced but not styled here; styling is assumed to live in the bundled CSS.

Pull submitted values out of a parsed urlencoded body and write them into the form’s fields.

Render the .field-error block for a single message. Empty msg → empty string, so callers don’t need to gate the call.
