fix: exclude trailing quotes from URLs in error dialog

[thebtf]

Summary

• Fix URL regex in renderMessageWithLinks that captured trailing ", ', }, ], > from JSON-embedded URLs
• Google API 403 responses include appeal URLs wrapped in JSON (e.g. "appeal_url":"https://..."), and the old regex /(https?:\/\/[^\s]+)/g would include the trailing quote, producing invalid links

Changes

• AccountErrorDialog.tsx: Changed regex to /(https?:\/\/[^\s"'}\]>]+)/g

Test plan

• Trigger 403 with appeal URL → link in error dialog should be clickable without trailing "
• Verify "Invalid Dynamic Link" error no longer occurs when clicking appeal link
