🔧 refactor: Improve Params Handling, Remove Legacy Items, & Update Configs (#6074)

* chore: include all assets for service worker, remove unused tsconfig.node.json, eslint ignore vite config

* chore: exclude image files from service worker caching

* refactor: simplify googleSchema transformation and error handling

* fix: max output tokens cap for 3.7 models

* fix: skip index fixing in CI, development, and test environments

* ci: add maxOutputTokens handling tests for Claude models

* refactor: drop top_k and top_p parameters for claude-3.7 in AnthropicClient and add tests for new behavior

* refactor: conditionally include top_k and top_p parameters for non-claude-3.7 models

* ci: add unit tests for getLLMConfig function with various model options

* chore: remove all OPENROUTER_API_KEY legacy logic

* refactor: optimize stream chunk handling

* feat: reset model parameters button

* refactor: remove unused examples field from convoSchema and presetSchema

* chore: update librechat-data-provider version to 0.7.6993

* refactor: move excludedKeys set to data-provider for better reusability

* feat: enhance saveMessageToDatabase to handle unset fields and fetched conversation state

* feat: add 'iconURL' and 'greeting' to excludedKeys in data provider config

* fix: add optional chaining to user ID retrieval in getConvo call
