* feat(spire-server): support x509pop externalPKI ca bundle
Add externalPKI mode support to the x509pop node attestor configuration.
Allows operators to configure CA bundles for external PKI-based node
attestation via two approaches:
- Inline PEM content (chart creates and manages ConfigMap)
- Reference to existing ConfigMap with ca-bundle.pem key
Includes volume/volumeMount definitions for CA bundle mounting at
/run/spire/data/x509pop-ca-bundle.pem and unit tests for both modes.

* refactor: simplify x509pop externalPKI template guard logic
Remove nested conditional guard for ca_bundle_path rendering. When
externalPKI mode is enabled, ca_bundle_path is always rendered; if no
CA bundle is provided, SPIRE will fail at startup with a clear error.
Drop unit tests pending fix to the unit test framework (which currently
has issues loading values from chart, forcing overly-defensive template
guards for test compatibility). Tests can be re-added once framework is
fixed.

* refactor: simplify x509pop volume/volumeMount guard logic
Remove nested caBundle existence checks from volume and volumeMount
guard conditions. When externalPKI mode is enabled, volume/volumeMount
are created; if no CA bundle is provided, SPIRE fails at startup with
clear error (missing mount).

* refactor: reorder if/with clauses for clarity
Move if condition checks to outer scope before entering with blocks.
This is more idiomatic Helm pattern and avoids unnecessary context
switching if condition fails.

* refactor: simplify conditionals to match chart patterns
Replace complex toString/eq comparisons with simpler boolean checks that
match existing patterns in the chart (e.g., federation.tls.certManager.enabled).
Changes:
- .enabled checks: remove toString wrapping, use simple boolean test
- .mode checks: remove toString, use simple eq comparison
- .caBundle checks: simplify from 'ne (... | default "") ""' to simple boolean test
This aligns with chart conventions and avoids tripping broken unit test
framework that struggles with complex conditionals.

* test: resurrect x509POP unit tests with simplified conditionals
Re-add unit tests for externalPKI mode now that template conditionals
have been simplified to match chart patterns. Simplified conditionals
should be less fragile with unit test framework.
Tests cover:
- externalPKI with chart-managed CA bundle (inline)
- externalPKI with existing ConfigMap reference

* docs: regenerate spire-server README for x509pop caBundle params
Updated parameter documentation for nodeAttestor.x509POP section to
include new caBundle configuration options (inline bundle and existing
ConfigMap reference).
Auto-generated documentation based on @param comments in values.yaml.
