[#1001] Remove PendingDb in favor of `v_transactions` and `v_tx_output` Views (#1001)
Removes `PendingTransactionEntity` and all of its related components.
Pending items are still tracked and visualized by the existing APIs
but they are retrieved from the `TransactionRepository` instead by
returning `ZcashTransaction.Overview` instead.

`pendingDbURL` is removed from every place it was required. Its
deletion is responsibility of wallet developers.

`ClearedTransactions` are now just `transactions`.

`MigrationManager` is deleted. Now all migrations are in charge of
the rust welding layer.

`PendingTransactionDao.swift` is removed.

Implementation of `AccountEntity` called `Account` is now `DbAccount`

`ZcashTransaction.Overview` can be checked for "pending-ness" by calling
`.isPending(latestHeight:)` latest height must be provided so that minedHeight
can be compared with the lastest and the `defaultStaleTolerance` constant.

`TransactionRecipient` is now a public type.

protocol `PendingTransactionRepository` is removed.

`TransactionManagerError` and `PersistentTransactionManager` are deleted.

`OutboundTransactionManager` is deleted and replaced by `TransactionEncoder`
which now incorporates `submit(encoded:)` functionality

`WalletTransactionEncoder` now uses a `LightWalletService` to submit the
encoded transactions.

- added latest scanned time and latest block height
- sample app showing the new values alongside with the %
- unit tests fixed
- latestBlock() API added
- the transaction repository is no longer used to update the exposed values during the syncing

[#895] Add Sync Session ID Synchronizer State (#906)
Closes #895

Add Sync Session ID to `SynchronizerState`.

A SyncSession is an attempt to sync the blockchain within the lifetime of a Synchronizer.
A Synchronizer can sync many times, when synced it will refresh every ~20 seconds +- random padding.
each sync attempt will have a different UUID even if it's from the same instance of SDKSynchronizer.

**How are SyncSessions are delimited? With `SyncStatus` changes.**

changes from [`.unprepared`|`.error`|`.disconnected`|`.stopped`] to `.syncing` assign a new sessionID to the synchronizer.

Any other transitions won't.

`areTwoStatusesDifferent ` was refactored to a helper function of `SyncStatus`

**How are IDs generated?**

ID generation is not mandated but delegated to a protocol `SyncSessionIDGenerator`.
Tests inject their own deterministic generator to avoid test flakiness.

Default implementation of SyncSessionIDGenerator is

````Swift
struct UniqueSyncSessionIDGenerator {}

extension UniqueSyncSessionIDGenerator: SyncSessionIDGenerator {
    func nextID() -> UUID {
        UUID()
    }
}
````

**SyncSession Pseudo-Atomicity and thread safety**

SyncSession is a type alias of a GenericActor holding a UUID

````
typealias SyncSession = GenericActor<UUID>

extension SyncSession {
    /// updates the current sync session to a new value with the given generator
    /// - Parameters generator: a `SyncSessionIDGenerator`
    /// - returns: the `UUID` of the newly updated value.
    @discardableResult
    func newSession(with generator: SyncSessionIDGenerator) async -> UUID {
        return await self.update(generator.nextID())
    }
}
````

Closes #895

SessionTicker struct to control session transitions.

switching to `.unprepared` now makes syncID to be `.nullID`
