Brooklyn Nicholson 62fe9fd101 style(desktop,tui): fix all lint/type/formatting issues
Bring apps/desktop and ui-tui to a clean state for typecheck, eslint,
and prettier:

- Run prettier across both trees (printWidth/wrap drift; prettier is not
  CI-enforced for these JS projects, so main had accumulated drift).
- Apply eslint --fix for padding-line-between-statements and perfectionist
  import/export sorting.
- Manual fixes for non-auto-fixable rules:
  - remove unused node:net import in electron/main.cjs (uses Electron net)
  - replace inline `typeof import(...)` annotations with top-level
    `import type * as EnvModule` in two ui-tui test files
  - scoped eslint-disable no-control-regex on intentional sentinel/ANSI
    regexes (mathUnicode.ts, text.ts)
  - resolve react-hooks/exhaustive-deps per-case: correct swapped/missing
    deps, collapse redundant session.* members, and justified disables on
    settings mount-only data-load effects to preserve run-once behavior

No behavior changes; test pass/fail counts are unchanged from the main
baseline.
