Added multiple setting functions and fixed bugs

■Added a setting item in “Splash Page Settings” of the top page, plan pages, and fixed pages to allow users to select the content to be displayed at the top/bottom (1st/2nd row) respectively from images or text.
■Added the following settings to the plan list (Theme Options > Plan List Settings) displayed on the top page and the bottom of the plan details page.
1)You can now select the display position of the catchphrase and subtitle from the top, center, or bottom.
2) You can now set the background color when the list image is hovered.
※This change allows for color overlay when the image is hovered to maintain the visibility of the text.
■Fixed a bug in the plan detail page where the slider would not be displayed if the plan list was in slider format and there was a splash page.
■Fixed the bug that the search result list is not displayed when using the standard search widget.
