Ullrich Schäfer f283401076 Stop BRouter contention kills under rapid editing
When a user rapidly moves waypoints in the Planner, BRouter's
thread-priority watchdog kills older in-flight requests to free a thread
for newer ones, surfacing to the user as "operation killed by
thread-priority-watchdog" errors.

Two fixes:

1. Bump the BRouter thread pool on the dedicated host from 4 to 16.
   `BROUTER_THREADS` is now a Dockerfile ENV (default 4 for
   flagship/CI/dev) overridden to 16 in `infrastructure/brouter-host/`.
   The host has 32 GB of RAM and idle cores; 4 threads was a flagship-era
   constraint that no longer applies.

2. Cancel the previous in-flight `/api/route` request when a new one
   starts. `use-routing.ts` now keeps an `AbortController` in a ref,
   aborts it at the top of each `computeRoute`, and bails quietly on
   `AbortError` so the newer call drives state.

Together these eliminate both the "real" contention (at the BRouter
level) and the wasted work (BRouter computing a route the client no
longer cares about).
