Subject: [PATCH] Web: add meshcoretel.ru profile link button next to public
 key
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds a hidden `ℹ` button (meshcoretelProfileBtn) in the Public Key
field of the Info panel.  After initApp() finishes loading the
"Loading info..." section, the public key value is read from the
DOM and validated against /^[0-9A-F]{64}$/.  If it passes, an onclick
handler is attached that opens https://meshcoretel.ru/<PUBLIC_KEY>
in a new tab, and the button is made visible.  The button remains
hidden if the key fails to load or does not match the expected 64-char
uppercase hex pattern, so the UI degrades gracefully on any firmware
that does not return a valid public key.

The container div is changed from fieldline (2-column grid: 1fr auto)
to inline-actions (3-column grid: minmax(0,1fr) auto auto) to accommodate
the second action button without wrapping.
