Fix blank personal settings page from mismatched bundle names

@nextcloud/vite-config prefixes every entry name with the app id, so the
entry "workflow-deck-automation-personal-settings" was emitted as
js/workflow_deck_automation-workflow-deck-automation-personal-settings.mjs
while Util::addScript() was still asking for the unprefixed name. Nextcloud
found neither the script nor the style, so only the empty mount div rendered
and the settings page stayed blank.

Shorten the entry to "personal-settings" and pass the full on-disk basename
(APP_ID . '-personal-settings') to addScript()/addStyle(). Document the
prefix rule and the intentionally near-empty CSS entry stub in CLAUDE.md.
