deps(deps): bump the batch-updates group across 1 directory with 4 updates

[dependabot]

Updates the requirements on gunicorn, flask-admin, black and ruff to permit the latest version.
Updates gunicorn from 25.3.0 to 26.0.0

Release notes

Sourced from gunicorn's releases.

26.0.0

Breaking Changes

• Eventlet worker removed: The eventlet worker class has been dropped. Migrate to gevent, gthread, or tornado.

New Features

• ASGI Framework Compatibility Suite: New end-to-end compatibility test harness covering Starlette, FastAPI, Litestar, Quart, Sanic, and BlackSheep. Current grid passes 438/444 tests (98%).
• ASGI Test Suite Expansion: 134 additional ASGI unit tests covering protocol semantics, lifespan, websockets, and chunked framing.

Security

• HTTP/1.1 Request-Target Validation (RFC 9112 sections 3.2.3, 3.2.4):
  • Reject authority-form request-target outside CONNECT
  • Reject asterisk-form request-target outside OPTIONS
  • Reject relative-reference request-targets
• Header Field Hardening (RFC 9110):
  • Reject control characters in header field-value (section 5.5)
  • Reject forbidden trailer field-names (section 6.5.1)
  • Reject Content-Length list form (RFC 9112 section 6.3)
• Request Smuggling Hardening:
  • Tighten keepalive gate and scope finish_body byte cap
  • Keep _body_receiver alive across the keepalive smuggling gate so pipelined requests cannot re-enter a closed body
  • Address parser/protocol findings from a six-point WSGI/ASGI audit
• PROXY Protocol (ASGI): Enforce proxy_allow_ips and tighten v1/v2 parsing in the ASGI callback parser.
• Connection Draining: Drain the connection on close per RFC 9112 section 9.6 to prevent reset-on-close truncation.

Bug Fixes

• Body Framing on HEAD/204/304:
  • Keep Content-Length on HEAD and 304 responses (#3621)
  • Drop body framing on HEAD/204/304 even when the framework set it
  • Warn once when an ASGI app emits a body for a no-body response
• HTTP/2 ASGI:
  • Fix _handle_stream_ended to set _body_complete in the async HTTP/2 handler so request bodies finalize correctly on stream end
  • Add InvalidChunkExtension mapping and fast-parser support in ASGI tests (#3565)
• HTTP/1.1 100-Continue: Stop adding Transfer-Encoding: chunked to 100-Continue interim responses.
• WebSocket Close Handshake (RFC 6455):
  • Comply with the close handshake state machine
  • Close the transport after the close handshake completes
  • Fix binary send when the text key is None
• Early Hints: Validate headers in the early_hints callback to match process_headers; pass only the header name to InvalidHeader (#3588).
• ASGI Framework Fixes:
  • Fix ASGI disconnect handling for Django-style apps
  • Fix Litestar request handling (use raw ASGI receive for body/headers)
  • Fix Litestar HTTP endpoints for compatibility tests
  • Fix Quart headers endpoint to normalize keys to lowercase
  • Fix Quart WebSocket close test app (missing accept())
  • Fix duplicate Transfer-Encoding header for BlackSheep streaming

Updates flask-admin from 2.1.0 to 2.2.0

Release notes

Sourced from flask-admin's releases.

v2.2.0

New Features:

• SQLAlchemy filter classes (FilterEqual, FilterLike, etc.) now accept a dotted-path string for the column argument (e.g. FilterEqual(column="author.email", name="Author Email")); the path is resolved against the view's model and the necessary joins are added automatically.

Bugfixes:

• Fix a bug in v2.1.0 that caused UnboundLocalError in flask_admin.contrib.sqla.ModelView when an exception was raised during a create or update operation

Changelog

Sourced from flask-admin's changelog.

Updates black to 26.5.0

Release notes

Sourced from black's releases.

26.5.0

Highlights

• Add support for unpacking in comprehensions (PEP 798) and for lazy imports (PEP 810), both new syntactic features in Python 3.15 (#5048)
• Python 3.15 is now supported. Compiled wheels are not yet provided for Python 3.15, so performance may be slower than on existing Python versions. Wheels will be provided once Python 3.15 is later in its release cycle. (#5127)

Stable style

• Fix # fmt: skip being ignored in nested if expressions with parenthesized in clauses (#4903)
• Add syntactic support for Python 3.15 (#5048)
• Fix crash when an f-string follows a # fmt: off comment inside brackets (#5097)
• Preserve multiline compound statement headers when # fmt: skip is placed on the colon line (#5117)

Preview style

• Improve heuristics around whether blank lines should appear before, within and after groups of same-name decorated functions (such as @overload groups) in .pyi stub files (#5021)
• Fix blank lines being removed between a function and a decorated class in .pyi stub files (#5092)
• Prevent string merger from creating unsplittable long lines when a pragma comment (e.g. # type: ignore) follows the closing bracket (#5096)

Packaging

• Run CI on 3.15 (#5127)

Output

• Improve parse error readability by showing multi-line output with an error pointer. (#5068)
• Add SourceASTParseError to distinguish source parse failures from internal safety errors, improving error reporting when Black's lenient parser accepts input that ast.parse() rejects (#5080)

Blackd

• Return HTTP 400 (Bad Request) for source parse failures instead of HTTP 500, keeping HTTP 500 only for genuine internal safety errors (#5080)

Integrations

• Added documentation for doctest formatting tools and updated the integrations index to match (#4916)
