Geoblock improvements

[jvsena42]

Description

This PR adds setup to disable geoblocking checks entirely via GEO bool environment variable with value true or false.
Also fixes some flows when geoblocked

When using GEO=false, geoblocking checks via API are bypassed.
Defaults to true, preserving current default functionality.

Test cases:

• To all cases you need to set a VPN to USA or Canada
• Setting isGeoblockingEnabled = false makes the app ignore geoblock check
• The app should display a warning about geoblock on onboarding

No Lightning channels

1. Saving -> Transfer to spending button not visible
2. Qr sheet -> Spending balance -> click on receive on spending balance button -> display a toast error

Only Blocktant channels

1. Saving -> Transfer to spending button not visible
2. Qr sheet -> Should not display Unified QR
3. Qr sheet -> Spending balance -> click on receive on spending balance button -> display a toast error
4. Scan lightning QR code -> should not be able to send

Blocktank + external peer channels

1. Saving -> Transfer to spending button not visible
2. Qr sheet -> Should display Unified QR
3. Qr sheet -> Spending balance -> Should display qr
4. Scan Lightning QR code -> should be able to send according the outbound with the external node

Pull Request Overview

This PR introduces a centralized geoblocking management system through a new GeoService singleton, replacing the previous scattered isGeoBlocked property in AppViewModel. The implementation adds support for disabling geoblocking via the GEO environment variable and enforces geoblocking restrictions by filtering out Blocktank LSP channels when users are in restricted regions, while still allowing Lightning operations through external peer channels.

Key changes:

• Created GeoService as single source of truth for geoblocking state
• Added GEO environment variable support with compilation-time and runtime configuration
• Implemented LSP channel filtering throughout the app to restrict Blocktank usage when geoblocked
