Unable to normalize HIST1H3B K28M

### Describe the bug

Apologies for such a specific ticket.
The variation normalizer is unable to normalize this variant: HIST1H3B K28M (gnomad vcf: 6-26031978-T-A)

https://normalize.cancervariants.org/variation/normalize?q=HIST1H3B%20K28M

### Steps to reproduce

https://normalize.cancervariants.org/variation/normalize?q=HIST1H3B%20K28M

### Expected behavior

I would expect this variant to be able to be normalized because it is a SNV that leads to a simple protein consequence change (so it should be supported)

### Current behavior

it says unable to normalize :(

### Possible reason(s)

I have a hunch that this may be related to the fact that this gene has a LOT of aliases:
```
{
"query": "HIST1H3B",
"warnings": [],
"match_type": 80,
"service_meta_": {
"name": "gene-normalizer",
"version": "0.11.0",
"response_datetime": "2026-03-25 16:35:53.619126+00:00",
"url": "https://github.com/cancervariants/gene-normalization"
},
"gene": {
"id": "normalize.gene.hgnc:4776",
"extensions": [
{
"name": "aliases",
"value": [
"HIST1H3B",
"H3C1",
"H3C10",
"H3FL",
"H3C12",
"H3C8",
"H3C4",
"H3C3",
"H3C6",
"H3/l",
"H3C11",
"H3C7"
]
},
```

a very similar gene () also has some of the same aliases but is considered a different gene from the normalizer (and has a different hgnc id)
```
{
"query": "HIST1H3H",
"warnings": [],
"match_type": 80,
"service_meta_": {
"name": "gene-normalizer",
"version": "0.11.0",
"response_datetime": "2026-03-25 16:38:56.266681+00:00",
"url": "https://github.com/cancervariants/gene-normalization"
},
"gene": {
"id": "normalize.gene.hgnc:4775",
"extensions": [
{
"name": "aliases",
"value": [
"H3FK",
"H3/k",
"H3C1",
"H3C12",
"H3C2",
"H3C8",
"H3C4",
"HIST1H3H",
"H3C3",
"H3C6",
"H3F1K",
"H3C11",
"H3C7"
]
},
```

I actually wonder if the root issue here is in the gene normalizer after looking at the above output (maybe these should be the same concept?)...

but also when trying to normalize HIST1H3B K28M, I get this output in the variation normalizer:
```

Start by reproducing HIST1H3B K28M through the /variation/normalize endpoint and compare the result with the expected SNV normalization. Trace the gene-normalizer resolution and the SeqRepo lookups for the reported ENSP accessions; done means the variant returns a normalized result rather than being rejected.
