[feat](trx-frontend-http): overlay bookmarks on spectrum; enforce one per freq

Browse Source 
Draw bookmark frequency markers on the spectrum canvas: amber vertical
line + ribbon shape (rectangle with V-notch) at each bookmark in view.
Below the freq axis, show a #spectrum-bookmark-axis row of clickable
amber ribbon labels (clip-path bookmark shape); clicking tunes the rig.
Labels auto-appear / collapse as bookmarks scroll in and out of view.

Server: reject POST/PUT with 409 Conflict when another bookmark already
exists at the requested freq_hz (BookmarkStore::freq_taken helper).

Client: bmFetch() triggers a spectrum redraw so markers appear
immediately on load without requiring a tab visit first.
