fix(spend-permission): await wrapped async util in withTelemetry

[anilkaracay]

Problem

withTelemetry (the HOF wrapping the spend-permission utilities) is synchronous and does not
await the wrapped call. Because all 8 wrapped utilities are async, the completed telemetry
event fires on promise creation (wrong timing) and async rejections bypass the sync try/catch,
so error telemetry is never logged.

Change

Make the returned wrapper async and await the call inside the existing try/catch, mirroring
the repo's correct sibling HOFs (withMeasurement, withSignerMeasurement). The
telemetry === false passthrough is preserved. Public behavior is unchanged (the returned
promise resolves/rejects identically); only internal telemetry timing and error capture are fixed.

Testing

Added first-ever coverage in withTelemetry.test.ts (6 tests), written test-first:

• completed event fires only AFTER the wrapped async fn resolves (failed before the fix)

• error event is logged on async rejection (failed before the fix)

• started fires before completion (regression guard)

• telemetry === false passthrough returns the raw fn and logs nothing

• resolved value propagates unchanged

• function name derivation

• yarn test --run: full suite green (account package 74 files / 1006 tests; the 8 wrapped
  utilities' existing tests still pass)

• yarn format: clean (Biome)

• yarn build:packages: type-checks

Closes #361
