fix(menu): network picker blank rows — compact mode for networkmanager_dmenu (item 22)

Source-read of the pinned networkmanager_dmenu 2.6.2: with
compact = False (what our config.ini set) the script inserts literal
empty rows as separators between the ethernet/wifi/VPN sections —
the nameless entries Bernardo saw on the Latitude. compact = True
drops the separators and uses the unpadded row format, which also
renders better in rofi's proportional font than space-aligned columns.

Known residual, documented in config comment + HARDWARE-QUEUE: a
hidden-SSID AP still renders one nameless row (sec+bars only; the
name dedup keeps exactly one, and no config option filters it). If the
V3 retest still shows it, the follow-up is a small source patch
skipping empty-name APs in create_ap_list.

Verified: V0; V1 (rendered config.ini shows compact = True). Behavior
needs Wi-Fi hardware — V3 queued on the Latitude.
