feat(nodedeployment): add --genesis-override flag

[bdchatham]

Summary

Closes #183. Adds a dedicated seictl nd apply --genesis-override <key>=<value> flag that writes flat dotted-key entries into spec.genesis.overrides on the rendered SeiNodeDeployment. Mirrors the existing --override flag (which targets spec.template.spec.overrides).

Why

spec.genesis.overrides (shipped this morning via #181 + sei-k8s-controller#270) requires a flat map[string]<JSON> with dotted cosmos-module keys ("staking.params.unbonding_time": "600s"). The sidecar's applyGenesisOverrides enforces this: keys must be module.field[.field...], first segment must be a cosmos module in app_state.

seictl --set spec.genesis.overrides.<path>=<value> cannot emit that shape — --set's path parser splits unconditionally on . and builds a nested map. Today's first attempt at the field (sei-protocol/harbor-engineering-workspace#14) shipped the nested-map shape and the sidecar rejected it on every retry with key "app_state" must be of the form module.field[.field...]. Required a manual yq-patching workaround (sei-protocol/harbor-engineering-workspace#16).

What this PR does

seictl nd apply <name> --preset genesis-chain \
  --chain-id <id> --image <ref> \
  --genesis-override staking.params.unbonding_time=600s \
  --genesis-override bank.params.default_send_enabled=true \
  --genesis-override gov.params.voting_period_seconds=120 \
  --genesis-override mint.params.inflation='{"min":0.05,"max":0.2}' \
  -n eng-<alias>

Renders:

spec:
  genesis:
    overrides:
      "staking.params.unbonding_time": "600s"
      "bank.params.default_send_enabled": true
      "gov.params.voting_period_seconds": 120
      "mint.params.inflation":
        min: 0.05
        max: 0.2

• Keys are stored as literal map-key strings — no path splitting
• Values parse as JSON when they parse (numbers, bools, objects, arrays); otherwise as raw strings
• Local key-shape validation (module.field[.field...]) fails fast at apply time rather than after the SND has stalled
• Rejected when --preset != genesis-chain (rpc preset has no spec.genesis)
• Repeatable, distinct from --override

Tests

• TestRender_GenesisOverrideFlag — string / bool / number / object values all round-trip correctly through the renderer
• TestRender_GenesisOverrideRejectsNonGenesisPreset
• TestApplyGenesisOverride_Errors — missing =, empty key, single-segment key, empty path segment
• TestApplyGenesisOverride_PreservesExistingKeys — multiple flag uses accumulate into one map

make test passes.

Follow-ups

After this releases (v0.0.51?), the harbor-dev skill docs in sei-protocol/Tide get a follow-up PR that replaces the manual-yq workaround with the canonical --genesis-override invocation. Will land separately.
