* F541 fix remove unused workflow and combine linters into one add lnbits/static to ruff ignore remote setupnode ignore upgrades for mypy ignore F401 for __init__ files unused noqa ignore upgrades for black F821: undefine name disabled and logged webhook_listener for opennode and lnpay because they are obvisouly not working E402: module level import not at top of file fixup revert breaking changes wait for PR #1876 https://github.com/lnbits/lnbits/pull/1876 E721 fixes, only popped up for python3.9 not 3.10 [REFACTOR] core/__init__ to not have circular import issues WIP add db for backwards compat fix pyright make mypy happy again pyright did not catch those, i think mypy got confused with relative imports. maybe we should use absolute ones everywhere E402: module level import not at top of file dont forget to add core_app rebase on ruff pr f remo format * fix clnrest * ignore E402 in conftest * refactoring issues --------- Co-authored-by: jacksn <jkranawetter05@gmail.com>
