feat(runner): Container detection and handling, video bit-depth flags and script updates (#303)

## Description

Works in apptainer now.. podman is still the goat since apptainer needs
docker treatment and even more..

- Added container detection so podman can be used to it's fullest, the
non-sane ones are handled separately..
- Added video bit-depth option, cuz AV1 and 10-bit encoding go well
together.
- Some other package updates to nestri-server.
- General tidying up of scripts to make multi-container-engine handling
less of a pain.
- Updated old wireplumber lua script to new json format.

Further changes:

- Removed unused debug arg from nestri-server.
- Moved configs to config file folder rather than keeping them in
containerfile.
- Improved audio configs, moved some into wireplumber to keep things
tidy.
- Bit better arg handling in nestri-server.

## Summary by CodeRabbit

* **New Features**
* Optional 10‑bit video support and auto‑launch of an app after display
setup.

* **Changes**
* Standardized runtime/user env to NESTRI_* with updated home/cache
paths and explicit LANG; password generation now logged.
* Improved container/GPU detection and startup logging; reduced blanket
root usage during startup; SSH setup surfaced.
* WirePlumber/PipeWire moved to JSON configs; low‑latency clock and
loopback audio policies added; audio capture defaults to PipeWire.
  
* **Chores**
* GStreamer/libp2p dependency upgrades and Rust toolchain pinned; NVIDIA
driver capability exposed.
