EVSS PCIU Migration: Step 6b: Remove PCIU configuration and references from Vets-API (non-prefill)

[RachalCassity]

User Story

As a developer, I want to remove all references of PCIU to ensure Vets-API does not use PCIU, as we transition to VA Profile in preparation for the PCIU deprecation

Issue Description

PCIU configuration and references in Vets-API are no longer needed and should be removed to clean up the codebase and reduce unused configuration. This includes all references that are NOT related to prefill, including configurations and specs

remove_pciu flipper still allows PCIU data to fill in when data is missing. remove_pciu_2 does not allow PCIU data to fill in when data is missing. Any reference to both remove_pciu and remove_pciu_2 flippers will need to be removed with the following tasks:

Tasks

• Remove lib/evss/pciu
• Remove lib/evss/pciu_address
• Remove from rubocop
• Remove from breakers
• Remove from FormProfile
• Remove from User model
• Remove related spec files
• Remove redis configuration
• Remove settings config
• Tests are passing
• Test locally
• Test in staging

Acceptance Criteria

• PCIU configurations listed under the tasks have been completely removed from Vets-API

Moving out 2 sprints. This work should happen after ContactInformation is complete. ContactInformation is replacing PCIU, these tickets cannot be worked on until ContactInformation has been done and the PCIU has been replaced.

Contact Information V2 has to replace PCIU in prod before PCIU references can be removed.

Standup note: Moving this ticket to blocked status, as it is intricately related to and blocked by Step 6a. Also, Step 6a has a dependency with the mobile migration and testing and a draft PR can be created but it cannot be merged until the mobile work is complete.
Work on this ticket can start either after the draft PR is created for Step 6a, or after the mobile migration and testing is merged.

Sprint reporting note: this ticket is blocked until the mobile testing is complete. Moving out to Sprint 20, but I will comment & unblock this ticket if the mobile testing happens to get completed during Sprint 19.
