Adopt AGPLv3 and package native license and source notices

[frahlg]

The native app now uses AGPLv3 with the narrow Energyplan permission, retaining prior Apache rights in NOTICE. Both native interfaces expose source and license information. Android assets and iOS resources include LICENSE, NOTICE and LICENSING.md.

Official clean builds pin source links with GITHUB_SHA or -PftwSourceRevision; local builds default to development links. Extracted source builds without Git. Fork distributors must supply links to their own matching source. The license guide explicitly leaves app-store terms and any required alternative rights for review before store distribution.

Validation: shared JVM tests, Android debug APK and unsigned iOS simulator builds passed. Both application packages contain all three license documents. No physical-phone or app-store distribution test was performed.

Contribution guidance welcomes external PRs and requires new contributions to carry AGPL-3.0-only with the Energyplan permission. DCO sign-off grants no copyright assignment or commercial relicensing rights. NOTICE preserves the Apache-licensed default-branch snapshot at 1eec607d646b75188d6063e282dca786d50e8881, including its exact prior license and any prior notice.

This is part of the FTW license transition: AGPL-3.0-only for the open code, with a narrow section 7 permission for the proprietary Energyplan workers. Energyplan Home Use terms apply only to new workers; AGPL commercial use remains permitted. Prior Apache, MIT and Energyplan grants remain available, and third-party terms remain intact.

Automated legal review checked license scope, retained notices, source offers, the Energyplan boundary, commercial installer use and source packaging. It is not a human legal opinion and does not establish copyright assignments or app-store compatibility. Commercial rights can be offered only for software and rights Sourceful controls.

Paired PRs:

• FTW
• energyplan
• device-drivers
• ftw-webapp
• ftw-web

Note

Medium Risk
License relicensing and distribution obligations affect all contributors and distributors; app UI and build wiring are low-risk but store compatibility is explicitly unresolved.

Overview
Replaces Apache-2.0 with AGPL-3.0-only for the native app, adds the Energyplan combination permission in LICENSE, and documents the transition in new NOTICE and LICENSING.md. CONTRIBUTING.md and README.md now state that new contributions are AGPL+permission with DCO sign-off.

In-app compliance: shared generates SourceLicense URLs from GITHUB_SHA or -PftwSourceRevision (dev builds use repo main links). Android copies the three license files into assets and shows a Source & licenses dialog; iOS bundles the same files and a bottom disclosure with links to source and license.
