Keep blank pause errors inside conversation settings

[rustyorb]

An empty speech-pause field could trigger FastAPI's JSON validation response, and the settings form's 422 handler could insert that JSON into the page.

Send empty pause input through the existing form validation, mark the field required in the browser, and replace the settings card only for HTML validation responses. Also update the Windows handoff to reflect the latest screenshot confirming ESP-IDF 5.5.4 is active and COM15 is listed as USB Serial Device.

Validation: 42 tests and 10 subtests passed locally with the pinned upstream fixture. Scoped code review closed with no outstanding findings. The repository tree matches the tested local checkout. Firmware compilation and physical device checks remain Windows bench steps.

This is a small follow-up to merged PRs #3 and #2. It does not block starting the firmware build from main.

Summary by Sourcery

Keep conversation settings validation contained to the settings card and refresh the Windows firmware setup status.

Bug Fixes:

• Keep empty pause input within the settings form validation flow instead of returning an unhandled API validation payload.
• Restrict 422 response swapping to HTML validation responses so JSON errors are not inserted into the settings page.

Enhancements:

• Require a pause value in the browser settings form.
• Update Windows firmware handoff guidance to confirm ESP-IDF 5.5.4 and COM15 as the detected USB serial device.

Documentation:

• Refresh implementation and firmware build documentation with the latest ESP-IDF and serial-port verification details.

Reviewer's guide (collapsed on small PRs)

Reviewer's Guide

The PR fixes blank pause-field handling by routing empty input through existing validation, adding browser-side required validation, and limiting HTMX 422 swaps to HTML responses so JSON errors do not appear in the settings card. It also updates host and firmware documentation to reflect that ESP-IDF 5.5.4 is active and COM15 is the observed USB serial device.

Keep empty pause submissions in the normal form-validation flow and prevent non-HTML validation payloads from replacing the settings card.	Allow an empty pause field to reach application validation instead of FastAPI rejecting the request before the handler. Require pause input in the browser. Restrict HTMX 422 card replacement to responses with an HTML content type.	bridge/dashboard.py bridge/templates/host_settings.html
Synchronize Windows setup documentation with the confirmed ESP-IDF and serial-port state.	Record ESP-IDF 5.5.4 as active rather than requiring installation alongside 6.1. Retain COM15 identification and unplug/replug verification instructions.	docs/implementation-status.md firmware/STAKIA-BUILD.md
