Activity: Hide memos/keysend messages and notes when lurker mode is enabled

[myxmaster]

Description

Since we now display memos/keysend messages in Activity view, we need to care about hiding those in case lurker mode is enabled...

Notes also need to be hidden.

Regarding the last commit:
I overlooked that PrivacyUtils.sensitiveValues() already checks internally if lurkerMode is enabled, sorry.

Why do we need to convert to string?

[myxmaster]

When i don't do it, I get:

No overload matches this call.
  Overload 1 of 2, '(props: TextProps): Text', gave the following error.
    Type 'string | number | Date | undefined' is not assignable to type 'ReactNode'.
      Type 'Date' is not assignable to type 'ReactNode'.
  Overload 2 of 2, '(props: TextProps, context: any): Text', gave the following error.
    Type 'string | number | Date | undefined' is not assignable to type 'ReactNode'.
      Type 'Date' is not assignable to type 'ReactNode'.ts(2769)
Text.d.ts(115, 3): The expected type comes from property 'children' which is declared here on type 'IntrinsicAttributes & IntrinsicClassAttributes<Text> & Readonly<TextProps>'
Text.d.ts(115, 3): The expected type comes from property 'children' which is declared here on type 'IntrinsicAttributes & IntrinsicClassAttributes<Text> & Readonly<TextProps>'

I think this is because PrivacyUtils.sensitiveValue() can return string | number | Date | undefined (because of this line: if (!lurkerMode) return input;) and then <Text> would be unhappy about a Date type.
