* feat(budgets): add per-model tpm and rpm limit maps to budgets and customers
Budgets gain model_tpm_limit and model_rpm_limit (model name to whole number, 0 or more).
/budget/new, /budget/update, /budget/info and /customer/new carry them, and the auth
path loads a customer's maps onto UserAPIKeyAuth as end_user_model_tpm_limit and
end_user_model_rpm_limit so the limiter can enforce them in a follow-up.
* fix(budgets): keep org, team and project per-model limits in metadata; lock_timeout and type gate fixes
Organizations, teams and projects store model_tpm_limit / model_rpm_limit in their own metadata,
which the limiter reads, so the shared budget allowlist leaves those two fields to customers.
Migration starts with SET LOCAL lock_timeout. Mapping annotations and rebind-ok reasons satisfy
the type discipline gate. Customer info tests expect the two new budget keys.
* fix(organizations): keep stripping budget_id and flattening nested per-model maps on update
The update path pops every budget field from the organization row again, so a caller's budget_id
never changes the attached budget, and a nested litellm_budget_table still flattens the two maps
into org metadata. Drops the explanatory comment on CUSTOMER_ONLY_BUDGET_FIELDS.
* fix(types): keep basedpyright and ruff strict counts flat for the new budget fields
Reads the per-model maps off the end-user params with membership checks instead of .get on an
untyped dict, writes the inline customer budget through the client's typed jsonify_object, and
builds budget rows in handle_budget_for_entity with model_validate so the two Mapping fields never
receive object-typed kwargs.
* chore: drop unrelated reformatting from project endpoints
