Function SchemaForm

Renders an editable plugin-config form from a declarative field schema. Fully controlled; keys in value that are not in the schema are preserved, so hand-edited or newer config keys survive a round-trip through the form.

Per-field rendering and the serialized value each type produces:

• text — single-line text input; serializes to a string.
• number — numeric input; serializes to a number, or undefined when cleared (so the key is dropped from the YAML rather than sent as an empty string).
• textarea — multi-line input (rows, default 4) for bodies/templates/scripts; serializes to a string.
• radio — segmented button group for small always-visible enums (e.g. rate-limit strategy); serializes to the selected option's string value.
• select — native dropdown for longer enums (e.g. content_type); serializes to the selected option's string value.
• switch — boolean toggle with optional inline switchLabel; serializes to a boolean.
• list — add/remove rows of a single scalar input (field.item.type picks text or number); serializes to an array of strings or numbers (e.g. cors allow_origins → ["https://app.example.com"]). New rows start as '' (text) or 0 (number).
• objects — add/remove cards, each rendering the sub-inputs in field.fields; serializes to an array of records keyed by the sub-field keys (e.g. proxy-rewrite add_headers → [{ name, value }], basic-auth users → [{ username, password }]). New cards are pre-filled from each sub-field's default, else 0/'' by sub-field type; a numeric sub-field cleared to empty serializes as undefined.

Every field shows its label above the input and optional hint text below.
