Consider not mutating schema in client

Currently we dynamically remove the `description` field in the schema in the client. We should consider fixing the schema upstream and/or instrumenting VJSF to just ignore that field instead of mutating the schema.

Start at web/src/components/Meditor/utils.ts lines 30-32 and trace how the schema reaches VJSF. Determine whether the upstream schema or VJSF should own ignoring the description field; done means the client no longer mutates the schema while the field is handled as intended.
