[Feature] Sport-aware optional second-tap feedback

[shchukins]

Parent

Part of #82.

Idea

Add optional sport-aware second feedback question after the primary RPE tap.

Problem

RPE alone is useful but does not distinguish why an activity felt hard.

Cycling, running, and other sports can create different subjective strain patterns.

Proposed solution

After primary RPE, optionally ask one sport-specific question.

Cycling:

Legs?

• 🟢 Fresh
• 🟡 Heavy
• 🔴 Dead

Running:

Impact?

• 🟢 Light
• 🟡 Heavy
• 🔴 Beaten up

Other sports:

Energy?

• 🟢 Good
• 🟡 Low
• 🔴 Empty

UX constraint

Maximum three taps total.

The second question must be optional and must not block feedback completion.

Acceptance criteria

• sport type determines optional question
• user can skip or ignore second question
• answer is persisted in feedback_payload or compatible structure
• no complex questionnaire flow
