ref(preprod): Remove graduated preprod-frontend-routes feature flag

[NicoHinderling]

Followup to #109829

Summary

• Remove the organizations:preprod-frontend-routes feature flag which has been at 100% rollout
• Remove features.has() gating checks from 9 backend API endpoints
• Remove <Feature> component wrappers and feature checks from 7 frontend files
• Remove flag-related decorators, context managers, and feature-disabled tests from 14 test files
• Remove flag registration from temporary.py and from the feature_flags list in organization_trace_item_attributes.py

Since this flag is fully graduated, all gated code paths are already executing in production. This just removes dead gating code.

Does not touch the separate preprod-build-distribution-pr-comments flag.

Test plan

• pytest -svv --reuse-db tests/sentry/preprod/api/endpoints/ — 448 passed
• CI=true pnpm test static/app/views/preprod/ static/app/views/releases/list/index.spec.tsx — 15 suites, 140 tests passed
• rg "preprod-frontend-routes" — only CHANGES file (historical changelog)
• Pre-commit hooks pass on all 32 modified files

🚨 Warning: This pull request contains Frontend and Backend changes!

It's discouraged to make changes to Sentry's Frontend and Backend in a single pull request. The Frontend and Backend are not atomically deployed. If the changes are interdependent of each other, they must be separated into two pull requests and be made forward or backwards compatible, such that the Backend or Frontend can be safely deployed independently.

Autofix Details

Bugbot Autofix prepared a fix for the issue found in the latest run.

• ✅ Fixed: Unnecessary unrelated feature flag added to test fixture
  • Replaced the unrelated organization feature flag in the releases list test fixture with an empty features array because the component no longer depends on any org-level flag.
