Subject: [PATCH] fix: improve pager message display and encryption
 classification

Three issues caused POCSAG messages to be incorrectly hidden or
misclassified in the Device Intelligence panel:

1. detectEncryption used a narrow character class ([a-zA-Z0-9\s.,!?-])
   to measure "printable ratio". Messages containing common printable
   ASCII characters like : = / + @ fell below the 0.8 threshold and
   returned null ("Unknown") instead of false ("Plaintext"). Simplified
   to check all printable ASCII (\x20-\x7E) which correctly classifies
   base64, structured data, and punctuation-heavy content.

2. The default hideToneOnly filter was true, hiding all address-only
   (Tone) pager messages. When RF conditions cause multimon-ng to decode
   the address but not the message content, the resulting Tone card was
   silently filtered. Changed default to false so users see all traffic
   and can opt-in to filtering.

3. The multimon-ng output parser only recognized "Alpha" and "Numeric"
   content type labels. Added a catch-all pattern to capture any
   additional content type labels that future multimon-ng versions or
   forks might emit, rather than dropping them to raw output.
