What happened?

The current configuration in src/shared/api.ts for both vertex and gemini has incorrect config which causes it to report incorrect pricing . The json portions copied below from the api.ts have 4 bugs:

1. It uses cacheWritesPrice: 0.05 in vertex and skips cacheReadsPrice entirely which in later API cost calculations causes the cacheReadPrice to be inferred as 0 hence the cacheRead cost is not reported
2. cacheWritesPrice: 0.05 is also wrong because cache writes are free on these models
3. In gemini config, it uses 2 pricing tiers, which is incorrect. This model does not have context tiered pricing
4. The actual cacheReadsPrice in those tiers is also wrong. Should be 0.05, not 0.03.

vertex:
"gemini-3-flash-preview": {
maxTokens: 65536,
contextWindow: 1_048_576,
supportsImages: true,
supportsPromptCache: true,
supportsGlobalEndpoint: true,
inputPrice: 0.5,
outputPrice: 3.0,
cacheWritesPrice: 0.05,
temperature: 1.0,
supportsReasoning: true,
thinkingConfig: {
geminiThinkingLevel: "high",
supportsThinkingLevel: true,
},
},
gemini:
"gemini-3-flash-preview": {
maxTokens: 65536,
contextWindow: 1_048_576,
supportsImages: true,
supportsPromptCache: true,
supportsGlobalEndpoint: true,
inputPrice: 0.5,
outputPrice: 3.0,
cacheWritesPrice: 0.05,
supportsReasoning: true,
thinkingConfig: {
geminiThinkingLevel: "low",
supportsThinkingLevel: true,
},
tiers: [
{
contextWindow: 200000,
inputPrice: 0.3,
outputPrice: 2.5,
cacheReadsPrice: 0.03,
},
{
contextWindow: Number.POSITIVE_INFINITY,
inputPrice: 0.3,
outputPrice: 2.5,
cacheReadsPrice: 0.03,
},
],
},

Steps to reproduce
