TestAccount used two local state keys per app. With two keys sort.Slice
does a single compare-and-swap, so the test passed while the sort was
broken. A third key makes the test fail on the old code.

convertTKVToGenerated sorted the converted entries with a comparator that
indexed a parallel slice of raw keys. sort.Slice swaps only the slice it
sorts, so the comparator read stale keys and the output order changed
from request to request. Iterate the map in sorted key order instead.

1. Fix Seed Vault label, add Algorand or Solana in front
2. If coming in it's an algorand deeplink input, filter to show only algorand accounts
3. Add solana icon to left side of amount like algorand
4. While click on send algo then same account should not come.
5. delete old algorand seeds that don't exist anymore in seed vault on app start, you can probably do removal in same spot where solana seed vault is checking and deleting

Go 1.27 runs encoding/json on the v2 engine. echo's default serializer
calls json.NewEncoder(w).Encode, which builds each response in a single
buffer before writing it, and the v2 engine grows that buffer in small
steps. A 9.6 MB applications page allocated about 25 MiB per request.

Replace echo's JSONSerializer in NewRouter with one that streams each
response through json.MarshalWrite into a pooled 64 KiB bufio.Writer.
The encoder flushes every 4 KiB on its own, and writing a large
response to the connection in pieces that small made it slower than
before. DefaultOptionsV1 is the option set encoding/json itself uses,
so the bytes on the wire do not change.

9.6 MB applications page over loopback HTTP:

            time               allocated
  no gzip   14.4 ms -> 12.6 ms  25.1 MiB -> 51 KiB
  gzip      73.9 ms -> 71.6 ms  27.5 MiB -> 347 KiB

A status response is unchanged.
