LinuxSat Panel

# LinuxsatPanel v3.0.0


## ✨ New Features
- **Global addon search (GREEN button)** — on the main panel, searches the entire
  catalog across every category and shows the matches as a normal installable list.
  On category/script grids, GREEN jumps straight to the first matching tile,
  switching page automatically. New "Search" label + green button bar in all
  three skins (HD / FHD / WQHD).
- **Installed addons highlighted** — addon lists show already-installed packages
  in green, computed from the opkg/dpkg database when the list opens.
- **Update check on panel start** — runs in the background at startup and shows
  version, changelog and update instructions. (The check existed but had been
  disconnected; it is now enabled, asynchronous, and uses a correct numeric
  version comparison.)


## ⚡ Performance — no more GUI freezes
- All network work moved off the GUI thread via a new `AsyncCall`/`AsyncMixin`
  helper (background thread + eTimer delivery, auto-cancelled on screen close):
  - Addon catalog fetch (was blocking at panel open **and** on every category click)
  - Channel-list provider page scraping (Ciefp, Cyrus, Manutek, Vhannibal, …)
  - Package downloads before install
  - The whole settings install (download / unzip / copy)
  - System information collection (public IP lookups, connectivity probes)
- **Catalog cached per session** (5-minute TTL) and pre-warmed in the background
  at panel open — category clicks are instant.
- Offline boxes no longer wait ~20 s of network timeouts when opening the
  Information screen; public-IP lookups are skipped entirely when offline.


## 🛡️ Data safety
- **Settings install can no longer wipe your channel list.** New flow:
  download → verify (unzip exit code + archive must actually contain a
  `lamedb`/`.tv` payload; both zip layouts supported) → automatic backup of
  `/etc/enigma2` → wipe → install → automatic restore if the copy fails.
  Every failure path shows a clear message and leaves the box untouched.


## 🐛 Bug fixes
- **Grid navigation**: UP barely worked (it jumped to the last page from most
  positions, and on page 2 it snapped to the first tile); LEFT wrapped to the
  wrong tile. All four arrows rewritten: UP/DOWN move one row and keep the
  column across pages, LEFT/RIGHT wrap cleanly page-to-page.
- **Partial grid pages**: a last page with e.g. 14 entries showed 6 leftover
  placeholder icons; unused tiles are now hidden.
- **Yes/No dialogs**: LCN scan and skin check ran even when answering **No**;
  `LcnXX` also reopened with the wrong callback.
- **Skin check crash**: an eTimer was connected to the return value (`None`) of
  the already-executed check → guaranteed TypeError.
- **Update check**: versions were compared as strings (2.9.x would never see
  2.10.x; 2.10.x was offered a "downgrade"); the changelog was never parsed;
  an empty response crashed callers. All fixed (`version_tuple`).
- **Free C-line fetcher**: a missing comma merged two regex patterns into one
  broken pattern; a dead server raised instead of showing a message; duplicate
  server entries could be appended (missing `break`).
- **Package removal**: filenames without `_` lost their last character, so
  `opkg remove` targeted a nonexistent package.
- **Grid paging**: item counts that are exact multiples of 20 produced a
  phantom empty page.
- **LCNScanner**: the terrestrial bouquet restore after a settings install was
  a no-op (function defined but never called); `bouquets.tv` dedup compared a
  full path against name-only lines, appending a duplicate reference on every
  run; `#NAME` rename could never match; self-import in the ServiceScan hook.
- **Python 3 crashes**: gzip catalog responses (`StringIO` fed bytes),
  `b64decoder` padding (bytes + str), undefined `PY3` in `fetch_url` on py2.
- **Information screen**: missing values printed a bare "Unknown" with no
  field label (operator-precedence bug).
- **View-log prompt**: the eTimer opening File_Commander was a local variable
  and could be garbage-collected before firing — log viewer silently never
  opened. Timer now held on the screen instance.
- Network requests without timeouts (script updater, package fetch) could hang
  the GUI forever.


## 🧹 Code quality & cleanup
- **Grid engine unified**: six screens carried byte-identical copies of the
  20-tile grid machinery (~1,500 duplicated lines). It now lives once in
  `LPGridScreen`; `plugin.py` shrinks from ~5,100 to ~3,900 lines. Every future
  fix in this area lands once instead of six times.
- Removed dead `translate_utils.py` (imported by nothing and unimportable) and
  two byte-identical duplicate `sh/` scripts.
- Removed dead `keyNumberGlobal` (referenced a widget that doesn't exist).
- `__pycache__`/`*.pyc` added to `.gitignore`.


## 🔧 CI / Housekeeping
- Lint (ruff, pylint, autopep8) and the translation updater now run on
  `develop` too; the auto-commit workflows push back to the triggering branch
  instead of hardcoded `main`. Autotag remains main-only (tags = releases).
- Version bumped to **3.0.0** in `__init__.py`, `CONTROL/control`,
  `installer.sh` (update-check changelog included) and the README badge.
  Merging this PR will trigger the automatic tag + release.
