refactor(landing): remove kview-era placeholder cruft; promote dataset

Remove the inert notifications block (fake (4) count, dead SEE ALL NOTIFICATIONS button, single-item filter, 4 static sample cards with broken image paths), the inert sidebar items (Favorites/Comments/Notifications + hardcoded counter), and the inert header ? help icon. Drop the orphaned notification-*/validation-*/all-notification-button CSS rules and the unused ComboBox field and import. Reflow the SplitPane so the journal grid sits directly under the header. Make the Dataset prominent (18px, bold) and move it above the still-wired GitHub Status.
