fix: v0.9.3 plan usage instead of API-price cost; larger footer

- Footer shows "5h N%" when Claude sends rate_limits (Pro/Max); the
  dollar figure is an API-price estimate, so it is kept only for API-key
  billing. Sessions tooltip follows suit. Closes #40
- Bottom row: 40px, larger hints, bold 1rem usage meters with wider bars;
  narrow windows drop hints instead of clipping the meters. Closes #41
- bats setup unsets inherited DevDesk env so tests pass inside DevDesk

+  * Claude's footer shows 5-hour plan use instead of a dollar figure on a
+    Pro/Max subscription (#40). Claude Code's cost is an API-price
+    estimate, not a bill; it is still shown for API-key billing. The
+    Sessions tooltip follows the same rule.
+  * The bottom row is larger and easier to read (#41): 40px tall, larger
+    hints, and 5h/week usage meters in bold monospace with wider bars.
+    Narrow windows drop the least-used hints instead of clipping the
+    meters.
+  * Tests clear inherited DevDesk variables, so they pass when run from
+    inside a DevDesk session.
