fix: address code review issues across SSH parser, groups, and CI

- Decode percent-encoded credentials in SSH tunnel URL parser
- Handle IPv6 bracket notation ([::1]:port) in host-port parsing
- Fix moveUngroupedConnections to preserve grouped connection order
- Add duplicate-name guard to renameGroup
- Persist group collapse state to UserDefaults
- Fix selectedGroup to use cached allGroups instead of re-reading storage
- Fix Telegram heredoc leading whitespace in CI workflow
- Deduplicate NewGroupSheet by reusing CreateGroupSheet
- Add tests for percent-encoded SSH URLs, IPv6 hosts, and rename-duplicate
