Replace template launcher icon with the BaselineMS trend mark

[MustafaNazeer]

What

Replaces the stock Android Studio template launcher icon (green grid background plus robot head foreground) with a BaselineMS mark: solid design token primary #0B5FA8 background, white trend polyline with four data point markers above a light blue (#D3E3FD) baseline. The same design as the 512x512 Play Store icon asset staged for the Play Console listing, so the installed app and the listing match.

Details

• Both adaptive icon variants (ic_launcher, ic_launcher_round) reference the two replaced drawables, so one change covers both, plus the monochrome themed icon layer.
• Foreground geometry sits inside the 66 dp adaptive icon safe zone (all content within radius 31 of the viewport center against the 33 dp safe radius), so no launcher mask crops the mark.
• The per density webp icons (mdpi through xxxhdpi) are removed. With minSdk 31, the mipmap-anydpi adaptive icon wins resource resolution on every device this app can install on; the webps were unreachable template leftovers.

Verification

• assembleDebug BUILD SUCCESSFUL.
• aapt dump badging on the built APK shows every density bucket resolving to the adaptive icon XML.
• Visual check of the rendered mark approved against the 512 store icon asset and a circular mask preview.
• Live launcher rendering lands in the next user driven AVD walkthrough.
