Parse the user's comma-separated fixed-times text field into the
canonical list shape Entracte persists: validated "HH:MM" strings
(always 24h regardless of input format), deduped, sorted ascending.
Invalid entries are silently dropped so the textarea stays forgiving.
The parser accepts both 24h ("14:30") and 12h ("2:30 PM")
regardless of the display format.
