Details

40 files changed. The changes are complete and all tests pass. Here's a summary of what was done:

**`RepoGlobalConfig` and `GlobalConfig.OPTIONS` additions:**
- `checkedBranches`, `configValidationError`, `forkCreation`, `forkOrg`, `forkToken`, `inheritConfig`, `inheritConfigFileName`, `inheritConfigRepoName`, `inheritConfigStrict`, `onboardingRebaseCheckbox`, `optimizeForDisabled`, `persistRepoData`, `productLinks`, `reportFormatting`, `reportPath`, `reportType`, `repositoryCache`, `repositoryCacheType`, `unicodeEmoji`

**Fields removed from their old interfaces:**
- From `RenovateSharedConfig`: `configValidationError`, `productLinks`, `repositoryCache`, `repositoryCacheType`, `unicodeEmoji`
- From `LegacyAdminConfig`: `onboardingRebaseCheckbox`, `optimizeForDisabled`, `persistRepoData`
- From `RenovateConfig`: `forkToken`, `inheritConfig*`, `checkedBranches`, `reportFormatting/Path/Type`, `s3Endpoint`, `s3PathStyle`, `configFileNames`, `toolSettings` (the last four were already in `RepoGlobalConfig` but duplicated)
- From `RepoParams`: `forkToken`, `forkCreation`, `forkOrg`

**`InheritConfig`** was already complete — all 11 `globalOnly && inheritConfigSupport` options were already present.

**Access patterns updated** in ~20 source files to use `GlobalConfig.get('fieldName')` instead of `config.fieldName`. All test files updated to use `GlobalConfig.set({...})` instead of setting these properties directly on config objects.
