Add paste-from-YouTube import to subscription section

Alongside the CSV option, add a text area that accepts copy-pasted text
from the YouTube subscriptions page. Extracts @handle from lines like
'@handle•N subscribers' using regex, deduplicates, then calls follow-bulk.
Button live-counts how many handles are detected as you paste.
