fix(vscode): move webview dev server off the cline hub port

The webview-ui vite dev server and WebviewProvider's DEFAULT_PORT both
defaulted to 25463, which is CLINE_HUB_PORT (25463 spells CLINE) — the
port the installed cline CLI's hub daemon listens on. With the daemon
running, vite silently bumps to another port on every F5. The .vite-port
file keeps the extension in sync so this mostly works, but it breaks
setups that need a predictable port to forward (e.g. VS Code attached to
a dev container, where the webview renders on the host and the dev
server runs in the container).

Move the default to 25465, clear of both CLINE_HUB_PORT (25463) and
CLINE_HUB_DEV_PORT (25466).
