perf: deduplicate bundles with the same contents

[wlawt]

depends on #123

problem:

• lots of same txns getting received and we're making a new and unique uuid:new_v4 for it and passing it to the audit topic

proposed solution:

• use uuid:new_v5 which we can pass in bundle_hash to generate the bundle ID. this would make the UUIDs deterministic
• have a TTL cache on the ingress layer that keeps track of known bundle IDs and expires after like 30s or something
• that way, we reduce the number of bundles of the same tx being sent to our audit workers

notes:
This doesn't affect a transaction thats contained across multiple bundles, for example:

 Bundle A = [tx1, tx2, tx3]
 Bundle B = [tx1, tx4, tx5]
 Bundle C = [tx1]

All have tx1 but the UUID will all be different (see how bundle_hash is computed)

maybe this can just be a simple LruCache with 1k size

or, look into https://docs.rs/quick_cache/latest/quick_cache/

found in: https://github.com/moka-rs/moka?tab=readme-ov-file#choosing-the-right-cache-for-your-use-case

could be more strict by having this be 10s which is 5 blocks (or 50 flashblocks) which is quite a long time

going to merge this into #123 as the experiment turned out fine
