MHSanaei 35e54f2e9a fix(frontend): match legacy wave animation timings + dark page bg
Two reasons the bottom wave looked static in dark/ultra-dark:

1. Animation durations were 7s/10s/13s/20s. Legacy uses 4s/7s/10s/13s.
   The 20s on the bottom wave was so slow that against the low dark-
   mode contrast it read as motionless. Restored the legacy timings.

2. --bg-page in dark mode was #151f31 (card color / surface-100), but
   the legacy .under uses surface-200 (#222d42) — that's the color of
   the bottom half of the page, the same as the wave fill, so the
   wave appears to flow into the page rather than meeting a hard edge.
   Now it does.
