neon12345 22a4b135f0 Accumulate smooth scroll into full wheel clicks on server 
fix(platform/ei): accumulate smooth scroll into full wheel clicks on server

On Wayland, two-finger smooth scroll events are delivered as per-frame pixel
deltas (e.g. 0.26, 0.53, 1.05 px per event).  The previous code quantized
these at the pixel level via `modf()` — any accumulated integer pixel (even
just 1) triggered a wheel event whose value was `pixels * 12`, i.e. 12, 24
or 36 units.  Because the deskflow protocol uses 120 units per standard
wheel click, these fractional clicks were silently dropped by the client
compositor and the user saw nothing on the secondary screen until a
very large/fast stroke pushed enough pixels through.

Switch to wheel-click-level accumulation: smooth scroll pixel deltas are
now scaled to fractional wheel-clicks (0.1 per pixel, keeping the 10 px ==
1 click convention) and only dispatched to the client when at least one
full 120-unit click has accumulated.  This uses `std::trunc()` (toward
zero) instead of `std::floor()` to avoid spurious clicks on negative
scroll values.

Physical mouse wheels (discrete scroll events, EI_EVENT_SCROLL_DISCRETE)
are unaffected and continue to be forwarded immediately as-is.

- `EiScreen.cpp`: replace `modf()` pixel quantization with fractional
  wheel-click accumulation using `std::trunc()`.
- `ScrollRemainder` struct comment: clarify the unit is now fractional
  wheel-clicks rather than pixels.
