refactor: tab-aware prioritized refresh system

Split monolithic refreshData() into independent sub-functions
(refreshCoreData, refreshAddressData, refreshTransactionData,
refreshEncryptionState) each with its own timer and atomic guard.

Per-category timers replace the single 5s refresh_timer_:
- core_timer_: balance + blockchain info (5s default)
- transaction_timer_: tx list + enrichment (10s default)
- address_timer_: z/t address lists (15s default)
- peer_timer_: encryption state (10s default)

Tab-switching via setCurrentPage() adjusts active intervals so
the current tab's data refreshes faster (e.g. 3s core on Overview,
5s transactions on History) while background categories slow down.

Use fast_worker_ for core data on Overview tab to avoid blocking
behind the main refresh batch.

Bump version to 1.1.2.
