fix(bibleverse): fix gui stack overflow after firmware update

Gui task stack is 4096 with 2800 free min. After recent driver migrations,
app overflowed:

- verse_buf[2048] on stack in show_current_verse
- bin_path[320]+idx_path[320] in load_book
- temp[512] in parse_books_json

Caused 'stack overflow in task gui' + LoadProhibited in sdmmc/stat path.

Fix:
- MAX_PATH 320 -> 128 (paths <80 chars)
- temp 512 -> 256
- verse_buf stack -> heap malloc/free
- ref buffers reduced

Also bump manifest to V2 (0.2) required by SDK 0.8.0-dev and versionCode 2.

Tested on 192.168.68.132 (ES3C28P): loads 66 books, displays verse, no reboot.
