Implement functional interface

[bckohan]

closes #156

[Copilot]

Pull request overview

Adds support for Python Enum’s functional (dynamic) API to enum-properties, extending it with a properties= keyword so dynamic enums can define named per-member properties at creation time (closes #156).

Changes:

• Implement EnumPropertiesMeta.__call__ support for EnumProperties("Name", names, properties=(...)) (and related mixins like FlagProperties).
• Add functional-API test coverage plus a runnable documentation example and how-to docs.
• Bump package version to 2.6.0 and update changelog/lockfiles.
