Create model definitions and user associations for (#20426)

* Removes Sidekiq Enterprise and Pro dependencies

Removes enterprise-specific Sidekiq gems and their dependencies (einhorn, gserver) to simplify the application's job processing infrastructure and reduce external dependencies.

* Adds user action tracking models and specs

Implements models to track user actions and events with:
- Status tracking (initial, success, error)
- IP address and user agent logging
- Association between actions and events
- Validation and dependency restrictions

Provides comprehensive test coverage including factories

* Restore original Gemfile.lock

* Update CODEOWNERS: Add user_action.rb and remove Gemfile.lock

* Update CODEOWNERS: Add user_action files with octo-identity ownership

* Fix CODEOWNERS: Add user_action entries in correct alphabetical order

* Fix CODEOWNERS: Update user_action entries to only use octo-identity team

* Update CODEOWNERS: Add spec files and ensure alphabetical order

* Removes trailing whitespace from model and spec files

Cleans up code style by removing unnecessary trailing whitespace characters at the end of files in:
- User action models
- Factory definitions
- Test specifications

This maintains consistent code formatting and follows Ruby style conventions.

* Update CODEOWNERS: Add factory files

* Fix CODEOWNERS: Move factory entries to correct alphabetical order

* Fix CODEOWNERS: Add parent directory entries and maintain alphabetical order

* Fix CODEOWNERS: Move user_action entries to correct alphabetical order

* Refactor UserAction and UserActionEvent specs

- Remove prefix from UserAction status enum for cleaner method names
- Update specs to use shoulda-matchers for associations
- Remove redundant tests for Rails built-in functionality (factory traits and enum transitions)

* Remove presence validations for IP and User Agent

- Remove presence validations for acting_ip_address and acting_user_agent

- Update tests to allow nil values for these fields

- These fields can be nil for system-initiated actions

* Use Faker gem in factories

- Use Faker::Lorem.sentence for user_action_event details

- Use Faker::Internet.ip_v4_address for IP addresses

- Use Faker::Internet.user_agent for user agents

* Update UserAction model to match new schema

- Remove UserAccount associations

- Add required SubjectUserVerification association

- Add optional ActingUserVerification association

- Keep IP address and user agent as optional fields

- Update tests to verify new associations and validations

* Add system_initiated trait for UserAction

- Add trait for system-initiated actions without user verification

- Set acting_user_verification, ip_address, and user_agent to nil

- Add comprehensive tests to verify trait behavior

- Ensure subject_user_verification remains required

* Remove system_initiated trait and its tests as requested

* Refactor UserAction specs to use let statements and contexts

* Removes trailing whitespace from spec files

* Refactor UserAction specs to use let statements and contexts

* Removes trailing whitespace in user action spec

* Update CODEOWNERS: Add user_action entries in alphabetical order

* Adds code owners for user action files

* Adds CODEOWNERS for UserActionEvent files

* Updates CODEOWNERS for user action files

* Assigns OCTO Identity team ownership for user actions

Removed duplicate code ownership entries

* Removes duplicate CODEOWNERS entries for user specs

* Simplifies enum status validation in UserAction

Reduces code duplication by leveraging Rails' built-in enum validation
functionality instead of custom validation rules. Consolidates status
validation tests to be more focused and maintainable.

* Adds newline at end of files

* Cleans up CODEOWNERS file redundancy and naming

* Simplifies user action specs with focused test cases
Removes unnecessary status predicate tests
Improves status enum testing with invalid status case

* Renames spec factory files to match plural convention:
- user_action_event.rb -> user_action_events.rb
- user_action.rb -> user_actions.rb

* Simplifies user action model specs

* Fix linting
