Fixes #13546

Proposed Changes

• Add a tipset_bloom table to the chain index DB for block-level ETH log blooms.
• Add a migration for existing chain index DBs.
• Compute and store tipset-level blooms while indexing actor events.
• Store empty blooms for indexed tipsets with no events.
• Rebuild/store blooms when previously reverted events are unreverted.
• Delete bloom rows on revert.
• Delete old bloom rows during chain index GC.
• Expose GetTipsetBloom on the chain indexer.
• Use indexed blooms when constructing ETH block responses for:
  • eth_getBlockByHash
  • eth_getBlockByNumber
  • new-head subscription block payloads
• Preserve compatibility by falling back to the previous full bloom when no indexed bloom is available.
• Extend TestTxReceiptBloom to cover receipt bloom, empty block bloom, block-by-hash bloom, and block-by-number bloom.

I started reviewing it, but I need to wrap my head around a few things.

Apart from that one comment, LGTM.
I haven't really worked on this part of the code much before, but it looks good.
