Add Typed Display Settings Administration

Browse Source 
Implements admin-only Display settings with generation-checked
Apply, Save, Load, Defaults, and Reset operations across the web UI,
CLI, SSH dispatcher, and local UI owner. Adds bounded HTTP handling,
session-isolated operation results, browser lifecycle support, and
comprehensive host tests and documentation.

When both transitions are enabled, `off-seconds` must be greater than `dim-seconds`. Applying settings counts as local UI activity. At normal boot, an initialized OLED shows a bounded five-second identity animation before the status UI begins; it scrolls the device name in yellow and draws the compact upright-terminal logo in blue. A missing OLED remains nonfatal; after reconnecting it safely, one new button press requests a bounded reprobe and is consumed without navigating.
Display settings require an available local UI task, not an attached panel. CLI and browser **Settings → Display** share the public configuration owner; concurrent mutations can report busy, and browser operations reject an intervening configuration edit rather than overwrite it. Save persists working RAM, not browser drafts. Load selects defaults when saved storage is absent/incompatible without rewriting NVS. Reset storage failure leaves RAM unchanged (commit-before-publication, no RAM rollback). Browser timeout/navigation does not cancel already-admitted work; Check Result and Refresh before retrying.
