fix(aura-gui): rename product to 'Aura' + uppercase SETENV in sudoers

Two bugs visible after user's first Install-admin-access click:

1) `visudo -c` rejected the fragment because sudoers tags must be UPPERCASE.
   We wrote `setenv:` (lowercase) which sudoers does not recognise as a tag
   and treats as a command path, producing a syntax error at column 29 of
   /etc/sudoers.d/aura-gui:2 — and worse, the broken file stayed on disk
   so every subsequent `sudo` complained about the syntax error too (sudo
   still functions but the warning is noise).

   Fix: drop the `setenv:` tag entirely. We never needed it — the GUI only
   passes RUST_LOG to the child via env(), which `sudo -E` would forward
   but we deliberately chose not to (smaller surface). Removing the tag
   also removes the failure mode.

2) Product rename per user feedback ("переименуй пакет на просто Aura"):
   - tauri.conf.json `productName` and window title: `aura-gui` -> `Aura`
   - bundle now produces /Applications/Aura.app and Aura_0.1.0_aarch64.dmg
   - identifier `ru.undergr0und.aura` was already correct, no change
   - sudoers file is now /etc/sudoers.d/aura (was aura-gui), so the success
     message and revert hint are updated accordingly

The internal MacOS/ binary is still named `aura-gui` (Tauri uses the Cargo
crate name there) — not user-visible, only the dev internals see it.

Manual cleanup also performed on the dev host:
- /Applications/aura-gui.app removed
- /etc/sudoers.d/aura-gui (the broken fragment from the first failed
  install attempt) removed via `osascript ... with administrator
  privileges` so sudo is no longer logging syntax errors
