Translate Pokegear's AM/PM too, and warn instead of corrupting a 3rd line

An independent review flagged two gaps:

Pokegear.lua's clock card (drawClock and the card-list clock view) prints
the same AM/PM information MainMenu's clock box does, but was left as bare
literals -- so a mod translating AM/PM would now show it correctly on the
title screen and in English on the Pokegear for the exact same hour. Both
call sites now go through Strings("AM")/Strings("PM"), the same source key
MainMenu.lua already added, so no new corpus entry is needed on the
translation-mods side.

SaveMenu.lua's twoLines() only ever split on the first "\n": drawPanel's
box has room for exactly two Chrome.print calls, so a translation needing
a third line (nothing in the current fr/de/es/it overrides does, but
nothing stopped one from trying) had nowhere on screen to go, and the
extra "\n" landed as a literal newline byte drawn as glyph garbage on the
second line with no indication anything was wrong. It now warns once per
source text instead.

Added a gen2_save_menu_translation_test.lua case driving drawPanel() with a
three-line mod translation: confirms only the first two lines render, the
warning fires exactly once (not once per frame), and drawing does not
crash. Pokegear.lua has no engine-tier test suite to extend for the AM/PM
change; verified by direct inspection and a syntax check instead.
