chore: Upgrade Rails to 7.2.2 and update Gemfile dependencies (#11037)

Upgrade rails to 7.2.2 so that we can proceed with the rails 8 upgrade
afterwards
 
 # Changelog
- `.circleci/config.yml` — align CI DB setup with GitHub Actions
(`db:create` + `db:schema:load`) to avoid trigger-dependent prep steps.
- `.rubocop.yml` — add `rubocop-rspec_rails` and disable new cops that
don't match existing spec style.
- `AGENTS.md` — document that specs should run without `.env` (rename
temporarily when present).
- `Gemfile` — upgrade to Rails 7.2, switch Azure storage gem, pin
`commonmarker`, bump `sidekiq-cron`, add `rubocop-rspec_rails`, and
relax some gem pins.
- `Gemfile.lock` — dependency lockfile updates from the Rails 7.2 and
gem changes.
- `app/controllers/api/v1/accounts/integrations/linear_controller.rb` —
stringify params before passing to the Linear service to keep key types
stable.
- `app/controllers/super_admin/instance_statuses_controller.rb` — use
`MigrationContext` API for migration status in Rails 7.2.
- `app/models/installation_config.rb` — add commentary on YAML
serialization and future JSONB migration (no behavior change).
- `app/models/integrations/hook.rb` — ensure hook type is set on create
only and guard against missing app.
- `app/models/user.rb` — update enum syntax for Rails 7.2 deprecation,
serialize OTP backup codes with JSON, and use Ruby `alias`.
- `app/services/crm/leadsquared/setup_service.rb` — stringify hook
settings keys before merge to keep JSON shape consistent.
- `app/services/macros/execution_service.rb` — remove macro-specific
assignee activity workaround; rely on standard assignment handlers.
- `config/application.rb` — load Rails 7.2 defaults.
- `config/storage.yml` — update Azure Active Storage service name to
`AzureBlob`.
- `db/migrate/20230515051424_update_article_image_keys.rb` — use
credentials `secret_key_base` with fallback to legacy secrets.
- `docker/Dockerfile` — add `yaml-dev` and `pkgconf` packages for native
extensions (Ruby 3.4 / psych).
- `lib/seeders/reports/message_creator.rb` — add parentheses for clarity
in range calculation.
- `package.json` — pin Vite version and bump `vite-plugin-ruby`.
- `pnpm-lock.yaml` — lockfile changes from JS dependency updates.
- `spec/builders/v2/report_builder_spec.rb` — disable transactional
fixtures; truncate tables per example via Rails `truncate_tables` so
after_commit callbacks run with clean isolation; keep builder spec
metadata minimal.
- `spec/builders/v2/reports/label_summary_builder_spec.rb` — disable
transactional fixtures + truncate tables via Rails `truncate_tables`;
revert to real `resolved!`/`open!`/`resolved!` flow for multiple
resolution events; align date range to `Time.zone` to avoid offset gaps;
keep builder spec metadata minimal.
- `spec/controllers/api/v1/accounts/macros_controller_spec.rb` — assert
`assignee_id` instead of activity message to avoid transaction-timing
flakes.
- `spec/services/telegram/incoming_message_service_spec.rb` — reference
the contact tied to the created conversation instead of
`Contact.all.first` to avoid order-dependent failures when other specs
leave data behind.
-
`spec/mailers/administrator_notifications/shared/smtp_config_shared.rb`
— use `with_modified_env` instead of stubbing mailer internals.
- `spec/services/account/sign_up_email_validation_service_spec.rb` —
compare error `class.name` for parallel/reload-safe assertions.
