Support OS 3.28 — update AppLoad sidebar QML hooks

[frapeti]

Summary

On reMarkable OS 3.28+, the current AppLoad release (v0.5.3) crash-loops xochitl during xovi startup:

[qmldiff]: Hashtab loaded! Cached 20341 entries
thread panicked: Couldn't resolve the hashed identifier 4073320026945606142
              required by AppLoad hooks in main UI

The Qt resource hashtab is present — the failure is that AppLoad’s sidebar hook targets no longer exist after the 3.28 UI refactor. This is separate from the hashtab rebuild issue reported in MaximeRivest/remagic#2.

This PR updates xovi/template/appload.qmd to hook into the new navigator/sidebar tree on 3.28.

Note: The same hook update was proposed in #59 by @rmitchellscott (tested on Paper Pro Move 3.28.0.157). This branch carries that patch plus independent verification on Paper Pro (Ferrari) 3.28.0.162. Happy to close this in favor of #59 once merged — the goal is to get a tagged release users can install.

What changed

• xovi/template/appload.qmd — retarget the AppLoad launcher entry in the main UI for the 3.28 QML tree (updated traverse/locate hashes, simplified sidebar button wiring, removed obsolete rebuild block).
• src/qtfb/fbmanagement.cpp — minor fix included in the same patch set.

Verification

Built appload.so for aarch64 with the reMarkable Ferrari SDK (5.7.119) and deployed to a Paper Pro (Ferrari), OS 3.28.0.162:

• /home/root/xovi/debug / /home/root/xovi/start — no panic
• Journal: [qmldiff]: Loaded external AppLoad hooks in main UI
• AppLoad icon appears in the sidebar; external apps launch

Compatibility

This hook update is breaking for OS ≤3.27 (as noted in #59). Recommend tagging a release clearly scoped to 3.28+ (e.g. v0.5.4-3.28) or documenting minimum OS in release notes until 3.28 is widespread.

This is a duplicate PR of #59 and appears to be AI slop.

You literally stole the commit from the other PR, then re-submitted it. 3.28 is still a beta, that's why #59 is not merged.
