Parse Docker ps output with tab-separated fields

[GT-610]

#1226

Summary

• Switch Docker ps output parsing to a tab-delimited format so long swarm names no longer break field alignment.
• Add a clear FormatException when a row does not contain the expected four fields.
• Extend tests to cover long swarm container names and malformed rows.

Testing

• Added unit coverage for tab-separated Docker rows with long container names.
• Added unit coverage for malformed row validation.
• Not run (not requested).

Summary by CodeRabbit

Summary

• Bug Fixes
  • Updated container listing parsing to align with tab-separated docker ps output.
  • Added clearer validation errors when rows are malformed.
  • Improved container refresh resilience by skipping only invalid rows instead of failing the entire update.
  • Adjusted docker ps command output to use status ({{.Status}}) and preserve image values correctly (including unusually long container names).
• Tests
  • Expanded coverage for parsing edge cases and malformed-row failures.

📝 Walkthrough

Walkthrough

Docker container listing commands now emit tab-separated ID, status, name, and image fields. DockerPs.parse consumes this format, validates that rows contain at least four fields, preserves field values without trimming the image, and no longer depends on the removed miscellaneous regex import. Container refresh skips malformed rows individually, and tests cover tab-delimited output, long names, malformed rows, and the status template.

In `@lib/data/model/container/ps.dart`:
- Around line 150-157: Update the Docker PS parsing flow around DockerPs.parse
and ContainerPs.fromRaw so malformed rows are handled independently: catch
FormatException for each raw line during the per-row mapping, skip or otherwise
discard invalid rows, and allow valid rows to continue parsing without setting
the overall parsePs operation to an error.

In `@lib/data/provider/container.dart`:
- Around line 490-491: Update the Docker command template in the
ContainerType.docker branch to use Docker’s human-readable {{.Status}} field
instead of {{.State}}, so ContainerStatus.fromDockerState() and DockerPs.parse()
receive values such as “Up 2 hours” and detect statuses correctly.
