Closes #17.

Summary

• make colored CJK catalog TUIs stable at wide and compact terminal sizes and honor no-color modes
• let Enter open the highlighted record and display the identifiers accepted by view
• bind OAuth callback redirects to the actual IPv4 loopback listener
• remove four unreferenced, obsolete TUI screenshots
• sync the current server OpenAPI contract and regenerate the Go client so CI drift checks are meaningful

Verification

• go test ./... -count=1
• go vet ./...
• GOFLAGS=-buildvcs=false go build ./cmd/life-ustc
• OpenAPI sync/regeneration produces a clean diff
• regression tests cover ANSI/CJK at 80x24 and 40x12, selection/open behavior, no-color output, list/view identifiers, and the real loopback socket address
• delegated PTY checks exercised 80x24 and 40x12 against the public API, including zero escape bytes under --no-color

Superseded by #22, which keeps the batched CLI fixes and additionally validates the exact server #498 OpenAPI companion branch. #22 is green.
