style: polish fzf pickers with color scheme, ghost text, and separators

Add shared FZF_COLOR theme and _fzf_base_args helper to unify styling
across endpoint and history pickers. Adds highlight-line, ghost text
placeholders, inline-right info, preview labels, and dim separators
between detail sections.
