fix(web): inherit terminal size in simple typography

[chrisdeeming]

What Changed

In basic typography mode, the terminal now inherits the monospace font size, matching its existing font-family behavior. Advanced mode keeps its separate terminal size.

Why

The Monospace font setting says it covers the terminal, but only the family changed it. The size continued using the hidden Advanced value.

UI Changes

Before	After
Terminal remains small at 18 px	Terminal follows the 18 px monospace size

Note

Inherit code font size for terminal in simple typography mode

In simple typography mode, the terminal now uses the code font size instead of its own independent font size setting. This applies to both the terminal viewport in ThreadTerminalDrawer and the terminal preview in the simple settings panel. A new resolveTerminalFontSizePreference utility in appearanceFonts.ts centralizes this logic, returning the terminal font size only when advanced typography is enabled.

Note

Low Risk
Small, localized appearance logic with tests; no auth, data, or API changes.

Overview
Simple typography now applies the code (monospace) font size to the terminal, matching how terminal font family already follows code in that mode. Advanced typography still uses the dedicated terminal size.

A new resolveTerminalFontSizePreference helper in appearanceFonts.ts mirrors resolveTerminalFontPreference. It is wired into the thread terminal drawer and the simple-settings TerminalFontPreview, with unit tests for both modes.
