Replace the watch app's menu UI with a single scrollable report page, add the config page

Report screen (ui_report_window.c, new): replaces the MenuLayer +
per-item drill-down windows (ui_menu_window.c/h, ui_card_window.c/h,
removed) with one continuously scrollable page mirroring the
interpreter's own text/HTML report - day significance, each transit's
narrative, the full Celtic Cross spread, and guidance last. Bigger/
bolder fonts throughout. Card images are a fixed 72px wide: a full-
display-width version was tried first but reliably crashes the real
PNG decoder ("PNG memory allocation failed") on actual hardware,
independent of the app's own heap or lazy-loading - 72px is the
hardware-verified ceiling.

Config page (pkjs/index.js): a self-contained `data:` URI settings form
for birth data/language/notification, submitting via AppMessage to the
existing app_message.c receiver. package.json needed
"capabilities": ["configurable"] for the Pebble mobile app to expose a
Settings entry for the sideloaded app at all - app_message.c's own
receiving logic was already correct. Added config_log() (config.c) to
confirm on-device, via APP_LOG, exactly which values a shown reading is
based on - both right after a config submission and at every app
launch.
