Fix unrecognised tags causing ValueError on container/user load

[Copilot]

Any YAML entry containing a tag not registered in the column ordering list (e.g. ENABLE_FUSE: True) crashed on startup with ValueError: <tag> present in DataFrame but not in reordering. The root cause was that both the ordering guard and the UI hardcoded a fixed set of known tags, requiring a code change for every new tag added.

Changes

• yamlhandler.py (load_users and load_containers): Replaced the strict ValueError guard with a dynamic effective_order that appends any unknown columns to the end of the known ordering. No code changes are needed when new tags are introduced in the YAML.

• container.py: Rewrote the tags multiselect to discover boolean tag columns dynamically from the DataFrame. Well-known tags retain short aliases (DOCKER→ENABLE_DOCKER_ACCESS, PRIVILEGED→RUN_PRIVILEGED); any additional column not handled by a dedicated UI widget (e.g. ENABLE_FUSE, or any future tag) appears automatically using its column name — without requiring any code changes.

# yamlhandler.py — before (crashes on unknown tag)
for k in df.columns:
    if k not in order:
        raise ValueError(f'{k} present in DataFrame but not in reordering')
df = df[order]

# after (unknown columns appended automatically)
effective_order = order + [k for k in df.columns if k not in order]
df = df[effective_order]

@copilot you need to make this work for any new tag, do not just hardcode existing ones

Done. The fix is now fully generic:

• yamlhandler.py (load_users and load_containers): Replaced the ValueError guard with effective_order = order + [k for k in df.columns if k not in order] — any unknown column is appended automatically instead of crashing.
• container.py: The tags multiselect now discovers all boolean-style columns dynamically. Well-known tags keep short aliases (DOCKER, PRIVILEGED); any new column not in the explicitly non-tag set (e.g. ENABLE_FUSE, or any future tag) appears automatically using its column name.

No hardcoded additions needed for future tags.

Pull request overview

This PR prevents startup crashes when user/container YAML entries include previously-unregistered columns (“tags”) by making column handling and tag UI generation more dynamic, so new tags don’t require code updates to load safely.

Changes:

• yamlhandler.py: Replaces the strict “unknown column” ValueError guard with a dynamic effective_order that appends unknown columns to the end before reordering.
• container.py: Updates the “Tags” multiselect to build its options from the DataFrame columns, preserving short aliases for well-known tags.

container.py	Dynamically derives tag options from container DataFrame columns and maps well-known tags to short display aliases.
