feat(pyproject): add N (pep8 naming) rule to ruff config...

...Before it becomes too inconsistent.

Partially solves #34

It seems there is no clear choice for the attributes of the SQL Alchemy classes and we actually write them in 2 different ways:

• snake case (this is how it is presented in the SQLAlchemy documentation):

  diracx/diracx-db/src/diracx/db/sql/auth/schema.py

  Lines 40 to 48 in 34095d8

  	class DeviceFlows(Base):
  	__tablename__ = "DeviceFlows"
  	user_code = Column(String(USER_CODE_LENGTH), primary_key=True)
  	status = EnumColumn(FlowStatus, server_default=FlowStatus.PENDING.name)
  	creation_time = DateNowColumn()
  	client_id = Column(String(255))
  	scope = Column(String(1024))
  	device_code = Column(String(128), unique=True) # Should be a hash
  	id_token = NullColumn(JSON())

• camel case:

  diracx/diracx-db/src/diracx/db/sql/job/schema.py

  Lines 65 to 70 in 34095d8

  	class JobJDLs(JobDBBase):
  	__tablename__ = "JobJDLs"
  	JobID = Column(Integer, autoincrement=True, primary_key=True)
  	JDL = Column(Text)
  	JobRequirements = Column(Text)
  	OriginalJDL = Column(Text)

We should probably make an opinionated choice and specify it in CODING_CONVENTION.md.
Any opinion?

Needs: DIRACGrid/DIRAC#7968

snake_case ...?

[chaen]

snake_case definitely, BUT the reason for having the Camel case is the compatibility with DIRAC :-) it just started because of the prototype.
So indeed, the attributes should be xnake case, but the column name has to be Caml case

[aldbr]

Alright, I converted the attributes to snake_case and the column name in PascalCase.
So even the Auth SQLAlchemy classes, which are new, follow the same pattern in order to remain consistent.

I guess this error is expected: https://github.com/DIRACGrid/diracx/actions/runs/12135284425/job/33834028304?pr=334#step:14:205

Because I modified the DB schema of AuthDB. The pipeline should be fixed once the PR will be merged if I understand correctly (the new schema will be included in the diracx/services:dev image).
