Add filtering, paging, and richer output to all list commands

[151N3]

✨ This pull request was developed with the assistance of GitHub Copilot.

Summary

Upgrades all five list commands (cube, dimension, process, subset, view) with a consistent set
of new options, fixes a code bug, hardens the test suite, and patches a crash in the threads command.

New features

Shared utility (tm1cli/utils/list_utils.py)

New module with OutputFormat (yaml/json), VisibilityType (public/private/both), apply_filter,
apply_paging, and render_output — reused by all list commands.

Common new options on cube list, dimension list, process list

Flag	Description
--filter / -f	Case-insensitive regex or substring filter on names
--output / -o	Output format: yaml (default) or json
--limit	Maximum number of results
--offset	Number of results to skip (for paging)

Output format changed from one name per line to a YAML/JSON list (- Name).

subset list and view list — richer structured output

• Positional dimension_name / cube_name arguments replaced by optional --dimension / --cube
  flags; omitting them iterates over all non-control dimensions/cubes.
• New --type / -t flag: public (default), private, or both.
• Output is now structured records — each entry includes dimension/cube, name, and type.
• All four filter/paging/output flags also added.

process list — skip control TIs

New --skip-control-tis / -s flag to exclude processes whose names start with }.

dimension list

Flag renamed from --skip-control-cubes → --skip-control-dims (was a copy-paste mistake).

Bug fixes

process.py — duplicate Annotated import removed

from typing_extensions import Annotated was left in place after the new
from typing import Annotated, Optional was added, silently shadowing it.
The stale typing_extensions import was removed.

main.py — threads --beautify crash on empty list

threads[0].keys() raised IndexError when no threads were active for the current session.
Added an empty-list guard; prints "No threads." in that case.

Test improvements

tests/conftest.py

• MockedCubeService.get_all_names signature fixed to match the real API (skip_control_cubes kwarg).
• MockedViewService.get_all_names now returns a (private, public) tuple matching TM1py's actual return type.
• MockedSubsetService.get_all_names extended with hierarchy_name and private parameters.
• MockedProcessService added with get_all_names, exists, get, and update_or_create.

New tests/test_cmd_process.py

8 mocked unit tests covering list/ls aliases, JSON output (--output json),
--filter, --limit, --offset, and exists true/false.

tests/test_tm1cli.py

• test_process_clone_not_exists converted to a mocked test: patches both TM1Service and
  resolve_database so the process-not-found path is reached before any database-lookup error.
• All 5 previously failing tests now pass.
