fix(ui): drop duplicate daemon log on the startup overlay

renderLoadingOverlay() rendered the daemon's recent output twice during startup:
a bare 4-line centered tail (section 2c, init/warmup only) and the styled
terminal-style box (section 4, always shown when the embedded daemon exists).
The bare tail was a strict subset of the box, so the same dragonxd output showed
stacked twice. Remove the redundant bare tail; keep the terminal box (which also
matches the shutdown screen's panel).
