Refactor repo filter UI and relocate Export CSV

Update dashboard UI in misc/data/dashboard.go: move the repository <select> into the quickfilter group, apply inline styling for a compact themed dropdown, and shorten option labels (remove environment suffixes). Add a separator span between the select and quickfilter buttons. Move the Export CSV button from the top controls into the footer to simplify the header layout and avoid duplicate export buttons.
