Models: SafeUser/SafePrintJob, PrintJobLog redesign, job_id→id, datetime timestamps, model-based request.state.user

[Copilot]

Replaces loose float timestamps and plain-dict user/job representations with properly typed Pydantic v2 models throughout the stack.

Models

models/user.py

• SafeUser — base model, all fields except password; holds the backward-compat _coerce_permissions validator
• User(SafeUser) — adds Optional[str] password

models/print_job.py

• PrintJobLog redesigned: id, timestamp, actor ("system" or user id), type (e.g. "job_created"), description (optional)
• PrintJob.job_id → PrintJob.id
• SafePrintJob — excludes cups_job_id and file (R2 path); available via PrintJob.to_safe()
• All float timestamp fields (created_at, updated_at, timestamp) → datetime

Backward-compat model_validator(mode="before") on every renamed/redesigned model transparently coerces old MongoDB documents on read — no migration required. Pydantic v2 natively coerces stored Unix epoch floats to UTC-aware datetime.

Tools & decorator

• get_user_by_id / get_user_by_email return SafeUser / User instances instead of dicts
• request.state.user is now a model instance — attribute access everywhere:

# before
request.state.user["id"], user["printer"]["credits"]

# after
request.state.user.id, user.printer.credits

• tools/printer.py — _create_log emits the new PrintJobLog schema; user-facing methods return SafePrintJob dicts via to_safe()
• tools/users.py — .timestamp() calls removed; datetime.now(utc) passed directly to models

Suggested change

	type: str # e.g. "job_created", "job_accepted", "job_rejected"
	type: str

[Copilot]

Removed in c23fea5.

[afonsoingles]

Suggested change

	now_ts = datetime.datetime.now(datetime.timezone.utc)
	now_ts = datetime.datetime.now(datetime.timezone.utc).timestamp()

[Copilot]

Reverted in c23fea5. Pydantic v2 still coerces the float to a UTC-aware datetime when building the model.

Both suggestions were applied in c23fea5 and are confirmed in the current state of the branch:

• models/print_job.py — type: str (no trailing comment)
• tools/users.py — now_ts = datetime.datetime.now(datetime.timezone.utc).timestamp()
