Fix naming inconsistency: replace "PushiIt" with "PushIt" throughout codebase

[Copilot]

This PR standardizes the naming throughout the codebase by replacing all instances of "PushiIt" with the correct "PushIt" spelling. The addon is called "Push It" but was inconsistently referenced as "PushiIt" in many places.

Changes Made

JavaScript Files:

• assets/backend.js: Updated all variable names, function names, and comments

  • window.PushiIt → window.PushIt
  • PushiItPublicKey → PushItPublicKey
  • waitForPushiIt() → waitForPushIt()
  • checkPushiIt() → checkPushIt()
  • PushiItBackend → PushItBackend
  • PushiItReset → PushItReset

• assets/frontend.js: Updated API object and variable references

  • window.PushiIt → window.PushIt (main API object)
  • PushiItPublicKey → PushItPublicKey
  • PushiItUserId → PushItUserId
  • PushiItTopics → PushItTopics

PHP Pages:

• pages/send.php: Fixed comments, JavaScript variables, and test message text
• pages/settings.php: Updated frontend integration code snippet
• pages/backend_notify.php: Fixed JavaScript variable names and function calls
• pages/index.php: Corrected page title from "Pushi It" to "Push It"

Documentation:

• README.md: Updated extension point examples from PUSHI_IT_* to PUSH_IT_*

Bug Fix:

• install.php: Fixed syntax error (removed stray "/") and updated table references

All changes ensure consistent naming throughout the codebase. The JavaScript API remains functionally identical, just with corrected naming.

Fixes #4.

You're absolutely right! Since the addon is still in development, backward compatibility concerns don't apply. The changes can be made without those considerations. Thanks for pointing that out.
