filters: Add filter to hashtag search timeline view (#1412)

Applied the content filters to the hashtag search timeline view, to filter out #nsfw-tagged posts on that view if the user has that setting enabled.

Testing of the fix
------------------

**PASS**

**iOS:** 17.0 (iPhone 14 Pro simulator)
**Damus:** This commit
**Test steps:**
1. Search for #sauna hashtag
2. Pick one post from results that contains multiple hashtags
3. Locally change nsfw filter in the code to another hashtag (I picked #homestead in this example) (This is to make testing easier)
4. Run app on simulator
5. Disable nsfw filtering
6. Search for the #sauna hashtag
7. Ensure that the post from step 2 is there
8. Turn on nsfw filtering
9. Search for the #sauna hashtag again. Ensure that post from step 2 is no longer visible
10. Switch keyword back to #nsfw in the code. Re-run app
11. Search for the #nsfw hashtag. No posts appear (timeline view is empty). (Not sure if this is the desired behavior, but seems reasonable)
12. Turn off nsfw filtering
13. Search for the #nsfw hashtag again. #nsfw posts should appear.
