Subject: [PATCH 1/4] chore(deps): bump platform to 2cc4cdcf8 (rust-dashcore
 309fac8)

Adapts dash-evo-tool to rust-dashcore 309fac8 API changes shipped via
platform rev 2cc4cdcf85ce62b437031671336bf622b3aafaa5.

API surface changes handled:

- `MasternodeListEngine::feed_qr_info` signature changed: now takes
  `&QRInfoBlockData` rather than an `Option<F>` height-lookup closure.
  Both call sites in `masternode_list_diff_screen.rs` now pre-populate
  the bundle via a new `build_qr_info_block_data` helper that resolves
  hash->height from the screen's cache/Core RPC and height->hash for
  cycle boundary blocks via `get_block_hash` (Core RPC).
- `MasternodeListEngine::rotated_quorums_per_cycle` is now a
  `BTreeMap<BlockHash, BTreeMap<u16, QualifiedQuorumEntry>>` (was a
  `Vec`). `render_last_commitments` now destructures the inner map
  directly and the quorum index comes from the map key.
- `AddressProvider::on_address_found` / `on_address_absent` are now
  `async fn` (via the trait's `#[async_trait]`). `WalletAddressProvider`
  is annotated with `#[async_trait]` and both callbacks made `async`.
- `sml::quorum_validation_error::ClientDataRetrievalError` was removed
  upstream. The only DET uses were inside the feed_qr_info closure that
  is now replaced wholesale; the import is gone.

No behavioural change - this is pure API adaptation. All existing SPV
fixes on this branch (DB fallback for start_spv, atomic BIP44 pool
extension, SPV restart on mid-session import) continue to behave
identically and their tests still pass.

Subject: [PATCH 2/4] fix(spv): reset filter_committed_height on Clear SPV Data
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

At rust-dashcore 309fac8, WalletManager gained an independent
filter_committed_height field. FiltersManager::new() reads
filter_committed_height() for its "already synced" guard; the field is
no longer derived from synced_height.

Previously clear_data_dir called update_synced_height(0), which
pre-bump effectively reset both fields via the trait's default impl.
Post-bump it only resets synced_height, leaving filter_committed_height
at its stale previous value. FiltersManager then logs "Filters already
synced to N" and skips the rescan, producing zero balance after a
Clear SPV Data.

Switch clear_data_dir to update_filter_committed_height(0), which
unconditionally sets the field and only bumps synced_height upward if
the incoming height is larger — exactly the semantics we need for a
rescan-floor reset.

Adds a regression test asserting filter_committed_height is lowered to 0
after clear_data_dir().

Subject: [PATCH 3/4] fix: address review feedback on skipped-rescan and QR
 cache

- spv/manager.rs: propagate try_write() failure in clear_data_dir
  instead of logging-and-continuing. A contended or poisoned RwLock
  would have left filter_committed_height stale in memory while the
  on-disk data was wiped, re-triggering the exact skipped-rescan bug
  this PR is meant to fix.
- ui/tools/masternode_list_diff_screen.rs: use get_block_hash_and_cache
  helper in build_qr_info_block_data so both engine block_container
  and caches are consulted/populated consistently; drops redundant
  direct RPC call and redundant block_height_cache write.

Subject: [PATCH 4/4] fix(masternode-diff): clear pending task on error returns

Error paths in `feed_qr_info_and_get_dmls` and the `MnListFetchedQrInfo`
handler returned early after setting `ui_state.error` without clearing
`self.task.pending`, leaving the pending spinner stuck after a failure.
Clear `self.task.pending = None` on every error return so the UI is
always returned to an idle state.

Also move `build_qr_info_block_data` above the `insert_mn_list_diff`
calls in the `MnListFetchedQrInfo` handler so a failure does not leave
the diff cache partially populated.
