Upgrade to latest Babel, webpack, and related packages

Upgrades:
- @babel/core and plugins: 7.14.x → 7.29.0
- webpack-dev-server: 3.11.2 → 5.2.3
- webpack-cli: 4.7.0 → 4.10.0
- webpack-merge: 5.7.3 → 6.0.1
- html-webpack-plugin: 5.3.1 → 5.6.6
- source-map-loader: 3.0.0 → 3.0.2
- Added @babel/plugin-transform-private-property-in-object to eliminate
  Babel "loose" mode warnings

Also fixes electron-builder bundle to exclude all node_modules except
explicitly needed native modules (better-sqlite3, bindings,
file-uri-to-path). This reduces the app bundle from 409MB with 39,105
files down to 205MB with only 52 files.
