Integrates NoiseModel to manager-based workflows

[ozhanozen]

Description

This PR adds NoiseModel support for manager-based workflows. To achieve this, I have:

• Added NoiseModel lifecycle management to ObservationManager.
• Added a Callable field, func, to NoiseModelCfg, which ObservationManager uses to assign the class instance within, similar to how it is done for ModifierBase.
• Renamed apply() to be __call()__, to be consistent with function-based noises and ModifierBase.

Fixes #2715 and #1864.

Note: I left the changelog with the entry [Unreleased] until the PR is given the green light.
