Add (i) info button to every tab, explained for the average user

New InfoPanel.svelte: shared (i) button next to each module's h2, toggling
a plain-language explainer with three sections — what this tab is, how to
use it, what to enter in each field. One component so tone stays
consistent across all 10 tabs instead of each screen inventing its own
help pattern.

Deliberately avoids fiqh/legal jargon in favor of concrete, everyday
framing (e.g. Hibah explained as "a gift you give right now, while you're
alive" rather than leading with the Arabic term) — written for someone
with no prior estate-planning or Islamic finance background, consistent
with the "convince a 100-year-old grandmother" usability bar already
established for this product.

Wired into: Coverage, Faraid, Assets, Wassiyah, Hibah, Family Waqf,
Nominate, Trigger, Claims (H2), Settings.

e2e-info.cjs: new suite verifying the info button appears, opens a
non-trivial explanation, and closes again on every one of the 10 tabs.
31/31 passing. Re-verified all five prior suites (32/32, 16/16, 12/12,
10/10, 10/10) — 111/111 total, no regressions.
