Identified and removed several unused named imports from `./config.js`,
`./constants.js`, and `./lists.js` in `js/app.js`.
Unused from config.js: isDevMode, ADMIN_SUPER_NPUB, ADMIN_DM_IMAGE_URL,
MAX_WALLET_DEFAULT_ZAP, ALLOW_NSFW_CONTENT.
Unused from constants.js: URL_FIRST_ENABLED, getTrustedSpamHideThreshold,
DEFAULT_AUTOPLAY_BLOCK_THRESHOLD, DEFAULT_BLUR_THRESHOLD,
DEFAULT_TRUSTED_MUTE_HIDE_THRESHOLD, DEFAULT_TRUSTED_SPAM_HIDE_THRESHOLD.
Unused from lists.js: ADMIN_INITIAL_EVENT_BLACKLIST.
These symbols were imported but not utilized within the file, or were
erroneously referenced via `this.` when the intended value was the
imported constant (which remained unused).
Verified with existing unit tests and manual inspection.
