fix: resolve integration test compilation + CI errors

Test compilation fixes (8 integration test files):
  1. Ambiguous float types — added f32/f64 annotations
  2. chrono API — replaced with_hour() with date_naive().and_hms_opt()
  3. Missing dev-dependencies — added sqlx + base64
  4. Generic parse — wrapped f32 comparison in parens
  5. Incorrect assertion — 3^5=243 > 100, changed nodes to 1000

CI fixes:
  6. Missing benchmark fixtures — created 3 files in fixtures/benchmarks/
  7. clippy absurd_extreme_comparisons — usize >= 0 always true
  8. authentik_jwt test — Option<SystemTime> type mismatch
  9. http_server tests — removed broken RBAC test module (types deleted)

Result: cargo build --all clean, cargo test --all --lib passes
