Update to FastAPI 0.115

This commit will update/upgrade from FastAPI 0.112 to
[FastAPI 0.115](https://fastapi.tiangolo.com/release-notes/).
FastAPI 0.113, 0.114, and 0.115 are included in the same inboard commit
because the updates in each release are all similar.

FastAPI 0.113-0.115 enable cookies, form fields, headers, and query
parameters to be declared with Pydantic models. Query parameters, for
example, have been
[supported](https://fastapi.tiangolo.com/tutorial/query-params-str-validations/)
for many versions now, but application authors usually had to encode
them as "kwargs" (keyword arguments) in every API endpoint function,
resulting in code duplication and the need for custom logic. Now that
[query parameter models](https://fastapi.tiangolo.com/tutorial/query-param-models/)
are supported, models can be declared once and reused multiple times.

There are still gaps here - although FastAPI now supports reusing query
parameters, it does not provide features for helping API endpoint
functions work with those query parameters. Query parameters are
often used to set up filter and sort clauses for relational databases.
The construction of `SELECT` statements from these query parameters is
still left up to application developers. The related package
[SQLModel](https://github.com/fastapi/sqlmodel), while it does combine
Pydantic and SQLAlchemy models, does not provide features for `SELECT`
statement construction at this time either. Other third-party packages
like [fastapi-filters](https://github.com/uriyyo/fastapi-filters) may be
helpful.
