Add two new panel sections to the java-tron-server Grafana dashboard to support metrics from tronprotocol/java-tron#6624: - Block Metrics: empty block rate, per-SR empty block count, avg transactions per block, transaction count distribution - SR Set Change: event table and cumulative totals by action
Add descriptions for the new metrics under "Blockchain status" and "Block status" sections so node operators can discover and use them.

Please change the default buckets to align with java-tron latest metrics

Done in ad334cb — bucket array updated to match the refined values in tronprotocol/java-tron#6730. Also note the dashboard panel was already realigned to the new boundaries in f9325c7 earlier in this PR.
The block_transaction_count histogram buckets in java-tron are being refined to [0, 20, 50, 80, 100, 120, 140, 160, 180, 200, 230, 260, 300, 500, 2000] (tronprotocol/java-tron#6730), densifying the 0-300 range for percentile interpolation in the typical per-SR TPS range. Update the Block Transaction Count Distribution panel to match: the old le="10.0" and le="1000.0" boundaries no longer exist in the refined array, so those queries would return nothing. Adopt 9 legend buckets aligned to the new boundaries (0, 1-20, 21-50, 51-100, 101-200, 201-300, 301-500, 501-2000, 2000+) so the panel makes use of the added 0-300 resolution.
Update the documented bucket array for tron:block_transaction_count to match the refined buckets in tronprotocol/java-tron#6730: [0, 20, 50, 80, 100, 120, 140, 160, 180, 200, 230, 260, 300, 500, 2000]. Per @Sunny6889's review on this PR.

Why are these changes required?
tronprotocol/java-tron#6624 introduces
tron:block_transaction_count(histogram) andtron:sr_set_change(counter) metrics. This PR updates the official Grafana dashboard template so node operators can import and use the new panels directly, reducing onboarding effort as suggested in this comment.This PR has been tested by:
