fix: rename red palette to magenta and add true red palette

[jeetburman]

This PR addresses issue #602 by renaming the existing red palette to magenta and introducing a new true red palette.

• Renamed existing red palette to magenta (pinkish-red hues)
• Created new red palette based on #F91313 (notification error color)
• Updated palette.ts to use magenta for error backgrounds
• New red palette provides true red colors for error states

Resolves #602

Notes for Reviewers

This PR fixes #602

The existing red palette contained pinkish-magenta hues (e.g., #ff385c, #FFB3B9). This has been renamed to magenta for semantic accuracy. A new red palette has been created using #F91313 as the base color, which is already used for notification errors and provides true red colors.

Changes are backward compatible - the magenta palette retains all the previous red values, and components using error states now benefit from more accurate red colors.

@saurabhraghuvanshii ,
I've updated the magenta palette to proper magenta (purple-pink) shades:

• magenta[70]: #FFF0FA (was #FFF0F0)
• magenta[60]: #FFB3E6 (was #FFB3B9)
• magenta[50]: #FF66CC (was #FF6179)
• magenta[40]: #E600AC (was #ff385c)
• magenta[30]: #B30086 (was #B3153D)
• magenta[20]: #800060 (was #8C0a2F)
• magenta[10]: #4D0039 (was #660624)

The magenta palette now uses true purple-pink colors instead of rose-red. The red palette remains unchanged with true red colors based on #F91313.

@jeetburman check shades here https://maketintsandshades.com/#colors=B32700&hashtag=0&steps=10 and issue is to rename exitsing shades without removing old shades because we are using that shades everywhere so it will break our current setup
