fix(analytics): self-heal posthog identify on distinct_id drift

The effect previously fired identify exactly once per lastAddress ref
change. If posthog ever lost or rewrote its persistence (reset from
elsewhere, re-init, SDK quirk) the refs would still hold the prior
address and skip re-identifying.

Compare posthog.get_distinct_id() against the wallet address on every
run and re-identify when they diverge. Replace the unconditional
__loaded early-return with a one-shot posthog.onFeatureFlags retry so
an early effect tick doesn't silently drop the identify intent.
