v0.17.0 — Doc tool auto-deploy + revert (mirror of Report)

Adds the same deploy + backup/revert mechanism as Report, but for the
local Documentation web tool :
  PROSERVE-source/_doc/  →  C:\xampp\htdocs\ProserveDoc\
  http://localhost/ProserveDoc/

Default DocumentationUrl in the launcher set to http://localhost/ProserveDoc/
so the Documentation sidebar tab works out of the box on a fresh install
without any manual config.

Implementation
- LocalConfig.DocToolConfig (HtdocsRoot/FolderName/AutoDeploy/MaxBackups,
  defaults to ProserveDoc folder, 3 backups kept).
- IDocToolDeployer + DocToolDeployer : near-duplicate of the Report
  deployer with SourceSubdir = "_doc". Reuses ReportTool's BackupInfo /
  DeployStatus / DeployResult / DeployProgress types so we don't fork
  the data model.
- MainViewModel : new install step 7 right after the Report deploy step,
  mirrors its progress reporting + error dialogs (silent on
  XamppNotFound since the Report step already warned for the same root).
- SettingsViewModel : DocBackupViewModel + Doc properties + RedeployDoc
  + Revert commands. Loads the doc backups list in background like
  the Report ones.
- SettingsDialog.xaml : new « OUTIL DOCUMENTATION » card under the
  « OUTIL REPORT » one in Avancés, with the same fields and backup table.
- Strings.cs : doc-specific status / progress / error labels in 5 langs ;
  reuses some labels from Report where the wording is identical.

Versions bumped to 0.17.0.
