Fix four critical bugs: array merging (#2281), AWS SDK logging (#2270), helmDefaults skip flags (#2269), and OCI chart versions (#2247) (#2288)

* fix: resolve issues #2281, #2270, #2269, and #2247

This commit addresses four critical bugs in helmfile:

1. **Issue #2281**: Fix array merging in --state-values-set
   - Problem: Arrays were being replaced entirely instead of merged element-by-element
   - Root cause: MergeMaps() didn't handle arrays, and mergo.Merge was used in some places
   - Solution:
     * Enhanced MergeMaps() with mergeSlices() and toInterfaceSlice() functions
     * Replaced mergo.Merge calls with MergeMaps in environment.go and create.go
     * Arrays now merge element-by-element, with nested maps merged recursively
   - Files changed:
     * pkg/maputil/maputil.go - Added array merging logic
     * pkg/maputil/maputil_test.go - Added comprehensive unit tests
     * pkg/environment/environment.go - Use MergeMaps instead of mergo.Merge
     * pkg/state/create.go - Use MergeMaps instead of mergo.Merge
     * test/integration/test-cases/issue-2281-array-merge/ - Integration test
     * test/integration/run.sh - Added new integration test

2. **Issue #2270**: Suppress AWS SDK debug logging
   - Problem: AWS SDK debug logs exposing sensitive information (tokens, auth headers)
   - Root cause: vals.New() called without LogOutput option
   - Solution: Set LogOutput to io.Discard in ValsInstance()
   - Files changed:
     * pkg/plugins/vals.go - Added LogOutput: io.Discard option

3. **Issue #2269**: Fix helmDefaults.skipDeps and helmDefaults.skipRefresh being ignored
   - Problem: skipRefresh only checked CLI flags, not helmDefaults or release settings
   - Root cause: Incomplete calculation at line 1559 in state.go
   - Solution: Added proper skipRefresh calculation mirroring skipDeps logic
   - Files changed:
     * pkg/state/state.go - Fixed skipRefresh calculation (lines 1522-1525, 1564)
     * pkg/state/skip_test.go - Added unit tests for skipDeps and skipRefresh

4. **Issue #2247**: Allow OCI charts without explicit version
   - Problem: OCI charts without version defaulted to "latest" which was then rejected
   - Root cause: getOCIQualifiedChartName() defaulted chartVersion to "latest"
   - Solution: Use release.Version directly without defaulting, only reject explicit "latest"
   - Files changed:
     * pkg/state/state.go - Remove default to "latest", use empty string
     * pkg/state/oci_chart_version_test.go - Added comprehensive unit tests
     * test/integration/test-cases/issue-2247/ - Integration test with registry
     * test/integration/run.sh - Added new integration test

Fixes #2281, #2270, #2269, #2247

* fix: correct integration test for issue #2281 array merging

The helmfile template needed to pass the 'top' values to the chart
so that .Values.top is accessible in the template context.

Changes:
- Pass state values to chart values using toYaml
- Adjusted indentation for proper YAML structure
- Template now correctly accesses .Values.top for array data

Test output now matches expected output with proper element-by-element
array merging.

* fix: make Helm version parsing more robust in issue-2247 test

Improved version parsing to handle edge cases in CI environments:
- Added fallback to 3.8 if version parsing fails
- Added default values for HELM_MAJOR and HELM_MINOR
- Prevents test failures due to version detection issues

This ensures the test runs correctly across different environments
and Helm versions.

* debug: add diagnostic output for issue-2247 test failure

Added debug logging to show:
- helmfile command output when it succeeds unexpectedly
- Helm version being used by the test

This will help diagnose why the validation isn't triggering in CI.

* fix: make OCI 'latest' validation work for all Helm versions

The validation for explicit 'latest' in OCI charts was depending on
helm.IsVersionAtLeast("3.8.0") which could fail if Helm version
detection has issues in CI environments.

Changes:
- Remove Helm version check from validation
- Always reject explicit 'latest' for OCI charts
- Remove Helm version check from integration test
- Update unit tests to expect 'latest' to fail for all Helm versions

This ensures consistent behavior across all environments and
Helm versions, fixing the CI failure where helm version detection
was problematic.

Fixes integration test failure in CI.

* fix: remove unused helm parameter from getOCIQualifiedChartName

Since the Helm version check was removed from the OCI validation,
the helm parameter is no longer needed in getOCIQualifiedChartName.

Changes:
- Removed helm parameter from function signature
- Updated all callers to not pass helm argument
- Removed unused mockHelmExec test implementation
- Removed unused imports (testutil, helmexec, chart)

This resolves the golangci-lint unparam error.

* test: update TestGetOCIQualifiedChartName to expect 'latest' rejection

Updated test case for Helm 3.7.0 to expect error when using 'latest'
since we now reject explicit 'latest' for all Helm versions, not just
>= 3.8.0.

This aligns the test with the updated validation logic that ensures
consistent behavior across all Helm versions.

* fix: handle set -e in issue-2247 integration test

The integration test script is sourced by run.sh which has `set -e`
enabled. When helmfile commands fail (as expected for validation tests),
the script would exit immediately before capturing the exit code.

This fix temporarily disables `set -e` around each helmfile command that
may fail, allowing proper exit code capture and validation.

This resolves the persistent CI test failure where the test would exit
at Test 1.1 without showing any error message.

Signed-off-by: Aditya Menon <amenon@canarytechnologies.com>

* fix: add set -e handling for helm commands in issue-2247 test

Extends the previous set -e fix to cover helm package and push commands
in the registry tests (Test 2.2). These commands can fail and need proper
error handling without triggering immediate script exit.

This ensures:
- helm package failures are caught and handled gracefully
- helm push failures are caught and handled gracefully
- Test can skip registry tests and pass with validation-only results
- set -e is properly re-enabled after each command sequence
