refactor(alert-history-alert-popover): migrate to css modules

* fix(authn): include base path in SSO callback and error-redirect URLs

The SAML ACS URL and the OIDC/Google redirect URLs were built from the
site URL host plus a hardcoded path (e.g. /api/v1/complete/saml), dropping
the base path. When SigNoz is served under a sub-path (global.external_url
with a path, e.g. https://example.com/signoz), the API is served at
<prefix>/api/v1/complete/<provider>, so the identity provider was told to
call back to a path without the prefix and hit a 404.

Thread global.Config into the SAML/OIDC/Google callback providers and the
session handler, and prepend global.Config.ExternalPath() to the callback
paths and the SSO error redirect to /login. Root deployments are
unchanged since ExternalPath() returns "" without a configured sub-path.

* fix(authn): run callbackauthn suite with base path

* refactor(tests): self-contained base-path fixture for callbackauthn

Move the base-path setup out of the shared create_signoz factory and into
a package-scoped signoz fixture in the callbackauthn suite's own conftest
(same pattern as rootuser/conftest.py). When --base-path is set the fixture
appends SIGNOZ_GLOBAL_EXTERNAL__URL and the url-config prefix locally;
without it it behaves exactly like the global fixture. The shared factory
and docker config are left untouched.

* test(authn): add base-path SSO integration suite

Adds a dedicated `basepath` integration suite that serves SigNoz under a
hardcoded /signoz prefix (SIGNOZ_GLOBAL_EXTERNAL__URL) and exercises the SAML
and OIDC happy-path logins end-to-end. Every SigNoz API call is issued under
the prefix and the IdP callback (ACS / redirect URI) is registered with the
prefix, so the flow only passes when the backend builds prefixed callback URLs.

The shared TestContainerUrlConfig and create_signoz factory are left untouched.
The suite's conftest shadows the same-named auth fixtures (create_user_admin,
get_token, get_session_context, apply_license) with base-path-aware variants and
reuses the Keycloak/browser fixtures, which are not under the base path.

Google SSO is not covered: it requires the real accounts.google.com issuer and
a real Google login, so it cannot run against the local Keycloak IdP; it shares
the identical path.Join(ExternalPath, redirectPath) callback logic that SAML
and OIDC validate.

* revert: drop in-place base-path wiring from integration harness

Removes the --base-path flag, TestContainerUrlConfig.base_path, the idp.py and
02_saml.py .get() changes, and the callbackauthn base-path conftest fixture.
Base-path SSO is now covered by the dedicated `basepath` suite, so the shared
harness (TestContainerUrlConfig, create_signoz, callbackauthn) is back to its
original root-only form.

* refactor(test): remove apply_license fixture

* refactor(test): extract base-path-aware auth factories

Extract the session-context / token / token-pair / admin-registration logic
in fixtures/auth.py into reusable factory functions that take an optional
base_path (token_getter, session_context_getter, tokens_getter, register_admin),
with the fixtures delegating to them. Default base_path="" is byte-identical for
existing callers.

The basepath suite's conftest now reuses these factories with the /signoz prefix
as thin one-line fixture overrides instead of duplicating the request logic.

* refactor(test): give base-path admin registration a distinct cache key

register_admin takes an optional cache_key (default "create_user_admin"); the
basepath suite passes a distinct key so that under --reuse the admin marker
cached against the signoz-base-path container is not restored for (or from)
other suites' default signoz instance.
