fix(eterra): increase default timeout 40s -> 120s for large geometry pages

- DEFAULT_TIMEOUT_MS: 40_000 -> 120_000 (1000 features with full geometry
  from Feleacu regularly exceed 40s on the eTerra server)
- Add timeoutMs option to syncLayer() for caller override
- syncLayer now passes timeoutMs through to EterraClient.create()

Fixes 'timeout of 40000ms exceeded' on TERENURI_ACTIVE sync.
