Add pirate mode Easter egg to trip report

Long-press the "Trip Report" header flips the narrative into pirate
dialect (☠ VOYAGE header, "Made X nm by the log", "Avast!" log-entry
prefixes, closing "Fair winds and following seas. Arr."). Long-press
again returns to standard nav voice. Seamanlike output remains the
default; pirate mode is purely opt-in.
