style(player): move "Made with ❤️ by miti99" into the footer section label

The attribution lives inside the closing section-label band now (with
hatch flanks on both sides) instead of as a separate page footer.
Link to miti99.com kept clickable, with hover styling to differentiate
it from surrounding label text. Drops the duplicated standalone
<footer> from / and /master.
