appview: validate repo description length (max 140 chars)

Monorepo for Tangled

The description field had no length validation, so long descriptions
would pass the form but fail at the DB INSERT (CHECK constraint) or
lexicon layer (maxGraphemes: 140), after the PDS record and bare repo
were already created. Add client-side maxlength and server-side rune
count validation to reject early and avoid partial rollback state.
