chore: update ruff and mypy

[AlexanderLanin]

Up to now local execution of ruff/mypy via CLI or via VS Code extensions produces very different results than execution via pre-commit. This PR does not address the underlying drift. Simply updating the versions used by pre-commit, and fixing the code along the way.

Note that I made individual commits to facilitate review.

Note2: I don't have the slightest idea why pypi/pypi/-/aiohttp-client-cache/0.14.2 is automatically added to DEPENDENCIES. It happens automatically and always.

Pull request overview

This pull request updates the development tools ruff (from 0.8 to 0.15) and mypy (from 1.8.0 to 1.19.1) to align local and pre-commit execution results. The PR includes necessary code changes to satisfy the new linter and type checker requirements.

Changes:

• Updated ruff version constraint from >=0.8 to >=0.15 and mypy from >=1.8.0 to >=1.19.1
• Migrated from Enum with multiple inheritance to StrEnum throughout the codebase
• Replaced Optional[T] type hints with T | None union syntax
• Updated cast() calls to use quoted string types for forward references
• Fixed type checking issues and improved type hints for better type safety

there is a comment in pyproject.toml why the new union syntax is not used in db/models.py

[tool.ruff.lint.per-file-ignores]
"**/db/models.py" = ["UP007", "TCH003"] # new optional spec is not yet supported by odmantic

unless something has changed, we need to keep it like that.

the version of ruff in pre-commit and the project diverged and I had not noticed. What I do in another project to prevent that is to use pre-commit hooks like that:

- repo: local
  hooks:
    - id: ruff
      name: Ruff Linter
      entry: ruff check --fix
      language: system
      types: [python]

that will use the version of ruff from your local venv.
The downside is you need to activate the venv when committing.

I was also thinking of using pyright instead of mypy.
The dependencies stuff is annoying, I think we can stop updating that file.

@netomi it seems those ignore-settings did not work for some reason. Anyway it was fixed in 1.1.0 just recently art049/odmantic#500

That's why I made this odmantic update commit.
