deployed_version never refreshes for devices with mdns: disabled: true

What happened?

The deployed_version shown in the dashboard comes from storage.esphome_version on disk. It gets updated in two ways:

• At compile/upload time, correct at the moment of flashing
• Via the mDNS TXT record, update_device_mdns() in zeroconf.py reads the version field broadcast by the device and refreshes the stored value

However, async_refresh_hosts() in dashboard/status/mdns.py explicitly skips devices with no_mdns: true, so path #2 never runs for them. The native API does expose esphome_version in DeviceInfoResponse, but the dashboard doesn't currently use it to update the stored version.

For no-mDNS devices, the "Deployed version" in the dashboard is stuck at whatever was compiled at last flash. If the device is later reflashed (via a different instance of the dashboard for example), the version badge may show "Update available" incorrectly or, never show it when it should.

How to reproduce

1. Disable mdns
2. Flash a new version
3. Remove the related json in .storage, or use the dashboard on a different device
4. See a potentially wrong 'Update' badge

Expected behavior

We could use the native API (when enabled) to refresh it. Alternatively, MQTT could also be used I believe when enabled.

Would a PR that refreshes esphome_version via the native API (for no-mDNS devices) be welcome ?
