feat(settings): modify "Page as Sleep Screen" to "Quick Resume" options (#2089)

## Summary

**What is the goal of this PR?**

Adds a clearer Quick Resume sleep-screen flow. The previous “Page as
Sleep Screen” behavior is now exposed as a dedicated `Sleep Screen >
Quick Resume `option, with the timeout-only behavior controlled by a
renamed `Quick Resume on Timeout `setting.

**What changes are included?**

- Adds `Quick Resume` as a new `Sleep Screen` option.
- Renames the old `Page as Sleep Screen` setting to `Quick Resume on
Timeout`.
- Changes that setting’s choices from `Never / After Timeout / Always`
to `OFF / ON`.
- Makes `Quick Resume on Timeout = ON` equivalent to the old `After
Timeout` behavior.
- Makes `Sleep Screen > Quick Resume` equivalent to the old `Always`
behavior.
- Automatically forces `Quick Resume on Timeout` to `ON` when `Sleep
Screen` is set to `Quick Resume`.
- Renames internal setting references from `seamlessSleepScreen` to
`quickResumeSleepScreen`.
- Updates translations for the renamed setting label.

**Additional Context**

- This is mostly a settings/labeling restructure around existing
behavior, not a new rendering path.
- The runtime quick-resume behavior still uses the existing saved
framebuffer / last-screen sleep flow.
- Review focus areas:
  - Sleep entry behavior from manual sleep vs timeout sleep.
- The automatic dependency where selecting `Sleep Screen > Quick Resume`
sets `Quick Resume on Timeout` to `ON`.

**New `Quick Resume` option for `Sleep Screen` will automatically set
`Quick Resume on Timeout` to `ON`**:

**Example where a different sleep screen setting like `Cover` can be
used in combination with the `Quick Resume on Timeout` setting**:
