fix: resolve MCP type field switching bug and improve UX feedback across all forms

mcpTypeFields() used getElementById('mt') but radio buttons only had name="mt",
causing all fields to disappear when switching server types. Replaced with
querySelector for checked radio. Also added loading spinners, inline messages
(replacing alert()), and state refresh after async operations in uWallet, uMcp,
lnkMcp, sOci, sGenai, sAdb, sMcp, embedFile, and embedReport.
