fix(arm): call mamba cmake by full path in pass 1 (apt 3.22 is too old)

The previous fix (install cmake via apt) didn't actually help: OpenMS
3.5's CMakeLists.txt requires cmake >= 3.24, and Ubuntu 22.04's apt
cmake is 3.22.1, which fails configure with

    CMake Error at src/openms/extern/CMakeLists.txt:11 (cmake_minimum_required):
      CMake 3.24 or higher is required. You are running version 3.22.1

That's exactly why the existing x86 Dockerfile installs cmake via
mamba (the conda-forge build is 3.30+). FLASHApp.arm escapes this by
using ubuntu:24.04 (apt cmake 3.28); we stay on 22.04 to minimize
churn vs. the working x86 Dockerfile.

Fix: in pass 1, call the mamba-env cmake by its full path
`/root/miniforge3/envs/streamlit-env/bin/cmake`. The plain-bash SHELL
is still in effect, so cmake doesn't pick up any conda-forge
environment side effects, and CMAKE_IGNORE_PREFIX_PATH keeps it from
auto-discovering miniforge libraries during find_package. The cmake
binary itself runs against miniforge's libstdc++, but that's a
runtime detail of cmake — it doesn't leak into the configured
project's link command.

The apt cmake addition from f11bc99 is now redundant but harmless;
leaving it in place to keep this diff focused.
