Wenxi d942a6d457 fix(plugins): keep MCP edits unsaved until connection succeeds (#16419)
## Description

Keep MCP setup and connection edits unsaved until authentication and
tool discovery succeed. In-form failures retain drafts and leave the
saved connection unchanged.

Changing Configuration again invalidates an older staged proposal.
Explicit Chat choices take priority over previous enable intents.
Successful authentication preserves unsaved tool edits. URL changes
clear old header values, and intentional OAuth navigation avoids a
discard warning. Remove unused legacy client wrappers and dead state.

Full-page OAuth failures require restarting authorization; this change
does not persist browser form drafts across redirects.

Setup failures use a neutral translated connection error when an
upstream response has no usable error detail. OAuth-specific errors and
safe backend details remain intact.

The shared browser-test helper follows staged setup responses and reads
the saved server ID after OAuth completes.

## How Has This Been Tested?

139 component tests and 49 selected service tests passed. Full
TypeScript checking/coverage, lint, formatting, and feature-map checks
passed. Backend transaction test limits are recorded in the parent PR.
Two focused Playwright helper checks passed for immediate connection and
pending authorization. A live local smoke test stopped at the existing
SSRF block on the local mock; security settings were unchanged. Full
browser CI is rerunning.
