refactor: delete dead non-RS validators; tests use RS variants

After v1.0.20 the non-RS validation chain had no production callers —
middleware.ServeHTTP dispatched exclusively through isUserAuthenticatedRS.
The orphaned functions stayed reachable only from a handful of test
files and risked silent logic drift against their RS counterparts.

Deleted from production code (~440 LOC):
  - auth_flow.go:        isUserAuthenticated
  - token_manager.go:    validateAzureTokens
  - token_manager.go:    validateGoogleTokens
  - token_manager.go:    validateStandardTokens
  - token_manager.go:    validateTokenExpiry
  - removed now-unused encoding/base64 and encoding/json imports
    from token_manager.go (only the deleted validateStandardTokens
    needed them; the RS variant in token_validation_rs.go keeps its
    own imports).

Added (3 LOC):
  - token_validation_rs.go: validateGoogleTokensRS (trivial delegator,
    parity with the deleted non-RS variant so isUserAuthenticatedRS
    can dispatch cleanly).

Tests ported (10 call sites across 3 files):
  - audience_test.go:                ts.tOidc.validateStandardTokens
  - azure_oidc_test.go:              tOidc.validateAzureTokens,
                                     ts.tOidc.validateGoogleTokens,
                                     ts.tOidc.validateAzureTokens,
                                     ts.tOidc.isUserAuthenticated
  - issue134_followup_graph_test.go: oidc.validateAzureTokens (4x)

Each ported site now constructs a *requestState from its existing
*SessionData via (&requestState{}).captureSession(session) and calls
the *RS variant. Same data, different read source.

Net diff: -440 LOC production, ~+25 LOC tests, +3 LOC stub.
Production now has a single source of truth for token validation;
no parallel implementations to keep in sync.

All tests pass with -race; golangci-lint clean.
