* fix: block NaN/Inf budget bypass and add missing non-admin guards
Addresses three security issues:
GHSA-wvg4-6222-3q4r: /user/update exposes max_budget, soft_budget, spend
to self-editing non-admin users with no server-side guard. Non-admin callers
now receive HTTP 403 if any of those fields appear in the update payload.
GHSA-q775-qw9r-2r4g: _enforce_upperbound_key_params returned early (no-op)
when upperbound_key_generate_params was absent from config, letting any
authenticated user generate a key with unlimited max_budget. Fix adds a
delegated-authority ceiling in _common_key_generation_helper: non-admins
cannot grant a key more budget than their own key carries.
GHSA-2rv4-xv66-fpjg: float('nan') passes every `value < 0` guard because
nan < 0 is False in Python, and spend >= nan is always False, permanently
disabling budget enforcement for any entity carrying a NaN max_budget.
All write-time budget guards now use `not math.isfinite(v) or v < 0`.
_enforce_upperbound_key_params validates finiteness unconditionally (before
the early-return). All spend-enforcement comparisons in auth_checks.py are
now guarded with math.isfinite(max_budget) as defense-in-depth.

* fix: close budget ceiling bypass for callers with no max_budget (GHSA-q775)
Non-admin callers whose API key has no explicit max_budget (None) could
bypass the delegated-authority ceiling and create keys with arbitrary
budgets. Now blocks budget assignment when caller has no budget configured.
Also removes redundant inline import of LitellmUserRoles.

* fix: only apply budget ceiling to explicitly requested max_budget
Capture the caller-supplied max_budget before _enforce_upperbound_key_params
can fill it with a default, so auto-filled defaults don't trigger the
ceiling guard for non-admin users with no budget on their own key.

* fix: capture requested max_budget before any defaults are applied
Move _requested_max_budget capture before both default_key_generate_params
and upperbound_key_generate_params mutations, so auto-filled values don't
trigger the ceiling check for non-admin users.

* fix: allow unlimited-budget callers to delegate any budget
Callers with max_budget=None (unlimited) can legitimately create
budget-capped keys. Only block when caller has an explicit budget
and the requested budget exceeds it.
