fix(deploy): preserve error typing through CDK wrapper and preflight

[Hweinstock]

Description

Problem

High rate of unknown errors from deploy in telemetry. There are a few places this could happen:

1. withErrorContext discarded all error typing by recreating errors as generic errors.
2. Preflight/teardown user errors were thrown as plain Error.

Net effect: deploy failures now carry their real type through to telemetry and error handling.

Documentation PR

N/A — no user-facing documentation changes; this only affects internal error typing/telemetry classification.

Type of Change

• Bug fix
• New feature
• Breaking change
• Documentation update
• Other (please describe):

Testing

How have you tested the change?

• I ran npm run test:unit and npm run test:integ
• I ran npm run typecheck
• I ran npm run lint
• If I modified src/assets/, I ran npm run test:update-snapshots and committed the updated snapshots

Notes:

• typecheck and lint pass on the changed files (wrapper.ts, actions.ts, preflight.ts).
• Full test:unit was not run cleanly in this environment due to a missing optional dependency unrelated to this change. The one failing test observed (LogsScreen > shows error when no runtimes are defined) reproduces identically on origin/main with these changes stashed, so it is pre-existing and not a regression.
