docs: document display.timeout and display.flip

Adds both settings to docs/cli_commands.md in the existing format, and records
the R8 dashboard, display controls and the two hardware fixes in the changelog.

The display.flip entry calls out that it is persisted config which survives a
firmware update, since a node still carrying flip=1 from testing looks exactly
like a firmware whose orientation was never fixed.

+#### View or change the display timeout
+**Usage:**
+- `get display.timeout`
+- `set display.timeout <seconds>`
+
+**Parameters:**
+- `seconds`: `0` to keep the display on permanently, or `1-3600` seconds of inactivity before it blanks
+
+**Default:** `60`
+
+**Note:** Observer builds with a display only. The change applies immediately and restarts the
+countdown. Tap the panel or press the USER button to wake or blank it by hand.
+
+---
+
+#### Rotate the display 180 degrees
+**Usage:**
+- `get display.flip`
+- `set display.flip <state>`
+
+**Parameters:**
+- `state`: `0`/`off` (as built) or `1`/`on` (rotated 180 degrees)
+
+**Default:** `0`
+
+**Note:** Observer builds with a display only, for a board mounted the other way up. This is
+persisted config, so it survives a firmware update - a node that looks upside down after an
+update may simply still be carrying `display.flip 1`. The boot log reports the current state.
