fix: reveal pairs oscillating between populated and empty

Two bugs found:
1. Individual name parts ("Ademo"→"John", "Demo"→"Smith") were added
   as reveal pairs, causing partial replacements that corrupted the DOM.
   The smart engine sends combined forms ("Ademo Demo"→"John Smith")
   which the catch-all already handles. Removed individual name entries
   from buildRevealPairs — only emails, usernames, hostnames, phones
   are matched individually.

2. Cache invalidated on every ss:config-updated (including settings-only
   changes like reveal toggle). Now only invalidates when mappings or
   identity actually change.
