unlock packages versions, use mypy strict

[lesnik512]

What's changed:

• unlocked package versions. Updated: lower constraints added
• .gitignore cleared from unused sections
• added poetry.lock to .gitignorу. Discussed here with @vrslev allow overriding in injections modern-python/that-depends#80 (comment)
• added justfile
• moved typing_extensions to dev section
• removed typing.Self from self annotation (it's not needed)
• full mypy strict with type ignores, where needed. This way we ignore only when required without missing any mypy warning
• fastapi.testclient.TestClient used for fastapi tests
