fix: use GOTHIC_28_BOLD for timer and green for goal-reached state

Two display bugs fixed:

1. Timer font: BITHAM_34_MEDIUM_NUMBERS overflows the 144-px display when
   all digits are wide zeros (e.g. "00:00:00"). Switch the timer layer to
   GOTHIC_28_BOLD once at creation — it fits both the 8-char "HH:MM:SS"
   countdown and the 9-char "-HH:MM:SS" overtime without truncation, so the
   per-refresh font swap is no longer needed.

2. Goal colour: theme_goal_background_color returned GColorOxfordBlue (dark
   navy) making the GOAL HIT overlay and GOAL REACHED timer state hard to
   distinguish from a plain dark screen. Changed to GColorIslamicGreen so
   both the overlay window and the post-goal timer background are vivid green,
   clearly signalling goal completion.
