Tolerate whitespace in pasted event ID lookups

The Load Event field requires 64 contiguous hex chars, but the event ID
printed on a tear-off tab wraps across two lines, so copying it back in
pastes as two 32-char halves separated by a newline/space and failed to
match. Strip inner whitespace before matching the raw hex id, which also
tolerates a pasted "Event ID:" label prefix. naddr/note/nevent inputs are
unaffected.
