Bump alembic from 1.17.2 to 1.18.0 in /server

[dependabot]

Bumps alembic from 1.17.2 to 1.18.0.

Release notes

Sourced from alembic's releases.

1.18.0

Released: January 9, 2026

feature

• [feature] [operations] When alembic is run in "verbose" mode, alembic now logs a message to indicate from which file is used to load the configuration.

  References: #1737

• [feature] [autogenerate] Autogenerate reflection sweeps now use the "bulk" inspector methods introduced in SQLAlchemy 2.0, which for selected dialects including PostgreSQL and Oracle use batched queries to reflect whole collections of tables using O(1) queries rather than O(N).

  References: #1771

• [feature] [autogenerate] Release 1.18.0 introduces a plugin system that allows for automatic loading of third-party extensions as well as configurable autogenerate compare functionality on a per-environment basis.

  The Plugin class provides a common interface for extensions that register handlers among Alembic's existing extension points such as Operations.register_operation() and Operations.implementation_for(). A new interface for registering autogenerate comparison handlers, Plugin.add_autogenerate_comparator(), provides for autogenerate compare functionality that may be custom-configured on a per-environment basis using the new EnvironmentContext.configure.autogenerate_plugins parameter.

  The change does not impact well known Alembic add-ons such as alembic-utils, which continue to work as before; however, such add-ons have the option to provide plugin entrypoints going forward.

  As part of this change, Alembic's autogenerate compare functionality is reorganized into a series of internal plugins under the alembic.autogenerate namespace, which may be individually or collectively identified for inclusion and/or exclusion within the EnvironmentContext.configure() call using a new parameter EnvironmentContext.configure.autogenerate_plugins. This parameter is also where third party comparison plugins may also be indicated.

  See alembic.plugins.toplevel for complete documentation on the new Plugin class as well as autogenerate-specific usage instructions.
