chore: get Android project building (toolchain, deps, manifest, launcher icon)

- Fix dependency versions (Retrofit 2.11, OkHttp 4.12, Compose BOM)
- Add Material Components for the app theme
- Add --add-exports/--add-opens for kapt on JDK 21
- Remove deprecated manifest package attr; add INTERNET permission
- Add adaptive launcher icon

+# Calendarr Android
+
+## Projektübersicht
+Android-App für den Calendarr-Server. Funktionsgleich mit der iOS-App (Swift, liegt unter ../Calendarr iOS/).
+Der Server-Code liegt unter ../Calendarr server/.
+
+## ⚠️ WICHTIG: Read-Only Ordner
+Die folgenden Ordner dienen NUR zur Referenz. NIEMALS Dateien darin verändern, löschen oder erstellen:
+- `../Calendarr iOS/` → READ ONLY – nur zur Analyse der Features und API-Nutzung
+- `../Calendarr server/` → READ ONLY – nur zur Analyse der API-Endpunkte und Datenmodelle
+
+Alle Änderungen und neue Dateien kommen ausschliesslich in `../Calendarr Android/`.
+
+## Server
+- Basis-URL (Prod): https://cal.scarriffle.com
+- Auth: Erst Server-URL eingeben, dann Benutzername + Passwort
+- Credentials werden auf Android im EncryptedSharedPreferences gespeichert (Äquivalent zu Apple Keychain)
+
+## Tech Stack
+- Sprache: Kotlin
+- UI: Jetpack Compose + Material 3
+- Architektur: MVVM
+- Netzwerk: Retrofit + OkHttp
+- Lokale Speicherung: EncryptedSharedPreferences (Credentials), Room (Cache)
+- Async: Coroutines + Flow
+- DI: Hilt
+
+## Projektstruktur
+- `../Calendarr iOS/` → READ ONLY – Swift-App als Referenz
+- `../Calendarr server/` → READ ONLY – Server als Referenz
+- `../Calendarr Android/` → dieses Projekt, hier wird gebaut
+
+## Git
+- Remote: https://git.scarriffle.com/Scarriffle/Calendarr-Android.git
+- Nach jeder abgeschlossenen Funktionseinheit committen und pushen
+- Commit-Messages auf Englisch, format: `feat: ...` / `fix: ...` / `chore: ...`
+- Niemals halbfertigen oder nicht-kompilierenden Code pushen
+
+## Build
+- Debug APK: `./gradlew assembleDebug`
+- Release APK: `./gradlew assembleRelease`
+- Tests: `./gradlew test`
+
+## Konventionen
+- Kein XML für Layouts – ausschliesslich Jetpack Compose
+- ViewModels dürfen keine Android-Framework-Klassen direkt referenzieren
+- StateFlow für UI-State, keine LiveData
+- Alle Strings in res/values/strings.xml
+- Vor jedem Push: `./gradlew build` muss fehlerfrei durchlaufen

+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/HEAD/platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
