User-reported install fixes:
- Branding: every user-facing 'SSO Manager' string now says 'Theta Directory'
(agent logs, CLI usage, agent.yml.example, installer wizard).
- Wizard page: the URL/join-key text boxes were never shown. The layout used
Surface.Width (0 at wizard init) instead of SurfaceWidth and combined
WordWrap with AutoSize (mutually exclusive in VCL). Rewritten with the
canonical Inno pattern (SurfaceWidth + ScaleY + explicit label height).
- No console window after install: the tray and helper now build as
GUI-subsystem binaries (-H=windowsgui) in build_all.sh and
scripts/setup-build-env.ps1. The agent stays a console app for foreground
debugging (as a service it never shows a console).
- The daemon never came up after install: install-service now starts the
service immediately, so the tray IPC socket exists right away and the tray
connects instead of logging 'actively refused' until a reboot.
Verified: go build/vet/test green; tray+helper PE subsystem = GUI (2), agent =
console (3); installer compiles; tray runs silently.
