ManuNotes 0.6.2

Changed

• Deck footer restyled. The "ManuNotes" label below the "+" tile now
  sits inside a solid rounded-rect (same width and corner radius as the
  "+" tile above it) instead of bare text, so it reads as a footer
  rather than another dashed, actionable slot in the stack.

Fixed

• A note with a mismatched encryption key made every other note
  disappear. loadAll() decoded every note in a single try, so one
  record that failed to decrypt (e.g. after a Keychain item was lost —
  a device restore, a corrupted item) silently emptied the whole list
  instead of just that one note. Bad records are now skipped
  individually and logged, and both the load and save paths now log
  failures instead of swallowing them with try? — this class of bug
  was completely silent before. Shared with iOS via ManuNotesCore.
