Refactor page titles and dialog close buttons across multiple views

- Replaced instances of `DialogCloseBtn` with `VDialogCloseBtn` in TransferHistoryView, AccountSettingAbout, AccountSettingSystem, and UserProfileView for consistency.
- Introduced a new component `PageContentTitle` to standardize page titles in SiteCardListView, SubscribeListView, UserListView, and WorkflowListView, improving layout and readability.
- Added keyword filtering functionality in SubscribeListView and SubscribeShareView to enhance user experience during searches.
- Added a new site logo image to the assets.
