Bug: the OLT flooding-mode and ONU-delete flows gated on window.prompt()
for the typed APPLY/DELETE confirmation, but Electron does not support
prompt() — it returns null and shows nothing, so clicking OK on the first
dialog silently fell through to "Cancelled." and nothing happened.
Fix: replace window.confirm + window.prompt with an in-app confirmTyped()
modal (Promise<boolean>). It combines the summary and the typed-word gate
into one dialog: the confirm button stays disabled until the operator
types the exact word; Enter confirms, Escape/backdrop cancels. Wired into
all three confirmations (OLT flood change, ONU delete, firmware execute).
Theme: shift the palette electric-blue, turn up the glow (stronger
multi-layer box/text shadows, bluer ambient vignette), and style the new
modal to match (neon border, red glow for destructive variant).
Verified: npm run check passes; rendered the login + modal offscreen and
functionally confirmed the typed-word gate enables the button and resolves
true on confirm.
