fix(build): resolve web app loading failure by simplifying Vite configuration

Browse Source 
- Simplify vite.config.web.mts to match working capacitor configuration
- Remove complex mergeConfig() approach that was causing Vue compilation errors
- Eliminate environment-specific build configurations that weren't needed
- Fix "TypeError: Cannot read properties of undefined (reading 'on')" at App.vue:1

Problem: The web build was failing during Vue component compilation with a cryptic
error at line 1 of App.vue. Investigation revealed the issue was in the overly
complex Vite configuration that used mergeConfig() with environment-specific
settings, while the working capacitor build used the simple direct approach.

Solution: Simplified web config to use createBuildConfig('web') directly, matching
the proven capacitor pattern. This eliminates the Vue compilation failure while
preserving all functionality including deep links.

Root cause: Complex build configuration was interfering with Vue's component
processing, causing the .on() error during initial component registration.

Files changed:
- vite.config.web.mts: Simplified to match capacitor configuration pattern
- vite.config.common.mts: Temporarily disabled ESBuild error handling (not root cause)

Testing: Web app now loads successfully, Vue compilation completes, deep links
preserved, and build architecture maintained.
