fix(timeline): clear required-field errors when the field is corrected

Browse Source 
titleError/dateError short-circuited on the server fail payload
(`form?.titleError ?? …`, `form?.dateError ?? ''`), so after a fail(400)
the red border and message stuck until the next submit even once the user
typed a valid value. Derive both from the current field value instead: the
server error still seeds the message, but a non-empty title/date clears it
immediately.
