refactor(app): remove legacy advanced fragments

[Foxpace]

Removes advanced recording and settings fragments superseded by the new Compose flows.

What was added

• Removal of advanced options, counters, measurement picker, annotation, and settings fragments.
• Removal of alarm and note UI handlers.

How it works

Measurement options, annotations, counters, and preferences now live in typed main state and are edited through Compose controls. User actions become intents, while domain use cases perform the recording behavior that was previously embedded in fragment handlers.

Superseded by #46, which targets master and shows the final current tree. Closing this stacked layer so review stays on the consolidated diff; this PR remains available as history.

Stack restored at the author's request. This PR is again part of the original 31-layer refactor chain. The architecture work continues as stacked PRs #47 through #54; consolidated PR #46 is superseded.
