Three pilot-surfaced issues in one pass:
1. PhoneParser regex used '\s' in the candidate character class, so a
digit on a following flattened line bled into the phone. '+7977
6277470\n1' (phone + trailing checkbox value) parsed as 12 digits,
producing '+797762774701'. Replaced '\s' with a literal space so
newlines/tabs stop the candidate.
2. Custom-themed forms don't use 'your-name' / 'your-email' keys
(washanyanya.ru has text-211 / text-212 / name_user). Added
FieldDetector::find_name + find_email as fallbacks. Classifier
and MessageFormatter now call them if no standard key matches,
so 'Александр' in text-211 is recognised as a cyrillic name and
scored / displayed accordingly.
3. FlamingoHelper copied '_from_email' into 'your-email' without
validating it. Flamingo derives that meta from whatever field it
considers "first"; on phone-first forms it ends up holding the
phone number. Now we only copy _from_email if it contains '@',
and dropped the _from_name shortcut entirely — FieldDetector
handles the name via the actual field values.
Tests: +1 FieldDetectorTest (13 cases); +2 PhoneParserTest cases for
newline/tab bleeds; +1 ClassifierTest case; +1 MessageFormatterTest
case for custom field keys. Full suite 53/53 green.
